1. Know the 4Cs

The first tip for buying a diamond engagement ring is to know the 4Cs: Color, Clarity, Cut and Carat Weight. Created by GIA, the 4Cs are the global standard for assessing the quality of diamonds and allow you to compare one diamond to another.

In brief, the 4Cs are:

  • Color: Color is graded on a D-to-Z scale, with D meaning that a diamond is completely colorless and Z meaning that a diamond has light yellow or brown color. In this color range, diamonds with less color are rarer and more highly sought-after.
  • Clarity: Diamond clarity refers to the absence of internal features, called inclusions, and surface irregularities, called blemishes. Clarity is graded on a scale from Flawless to Included.
  • Cut: The quality of a diamond’s cut determines how well it interacts with light. A diamond’s proportions, symmetry and polish determine its brightness (or brilliance), scintillation (or sparkle) and fire (flashes of color).
  • Carat Weight: Diamond carat weight determines a diamond’s apparent size. Generally speaking, the greater the carat weight, the rarer and more valuable the diamond, if the other Cs are comparable.

Once you understand what the 4Cs mean, the next step is to ask yourself “Which C is the most important to me?” Prioritizing the 4Cs will help you quickly eliminate some diamonds from your search and hone in on the diamond that’s right for you. It will also help you work with your budget, knowing which C you are willing to spend more on and which you are willing to compromise on.

2. Know diamond shapes and cut styles

Before you start shopping for an engagement ring, you should understand the difference between a diamond’s shape and its cutting style. Shape describes a diamond’s outline when viewed face up. The most popular diamond shape is round. But there are other shapes—known as fancy shapes—which include the marquise, pear, oval, rectangle, square and heart.

*Tip: Round brilliant diamonds tend to cost the most of all the shapes and cut styles. Choosing a fancy shape can be a good way to save money and choose a unique center stone.

Cutting style refers to how a diamond’s facets are arranged. The brilliant cut is popular due to how it maximizes a diamond’s brightness. This cut style can be seen on a range of shapes, from round to oval to square (princess cut) to marquise. The most popular shape and cut combination by far is the round brilliant cut, which has 57 or 58 facets.

The step cut is another popular cutting style. Steps cuts have long, sleek lines, which  gives them an elegant, sophisticated gleam. A popular step cut is the emerald cut—a square or rectangular shape with by concentric rows of parallel facets and beveled corners. In contrast, a radiant cut diamond also has a square or rectangular shape but is cut in the brilliant style.

*Tip: Step cuts tend to show their color and clarity more, while brilliant cuts are better at hiding color and inclusions. If you are purchasing a step cut, considering going up in color and clarity.

3. Look at diamonds under different lighting

Daylight, fluorescent light, spot lighting – a diamond looks very different under various lighting conditions. Many jewelers use white spotlighting, which brings out a diamond’s brilliance and fire and will make most diamonds look dazzling. Most day-to-day situations do not consist of such dramatic lighting, however. Be sure to see how your diamond performs under average lighting conditions, such as outdoors in light or shadow or under the diffused, fluorescent light of an office workplace or the warm, diffused lighting common in most homes.

Note that fluorescent lighting brings out a diamond’s brightness, while incandescent lighting brings out a diamond’s fire.

4. Pick a metal for the band

Popular jewelry metals include yellow gold, rose gold, white gold and platinum. Gold and platinum have different characteristics. Their colors can also change the appearance of a piece of jewelry and set off the color of a ring’s gemstones differently.

Metal Types:
Yellow gold is a classic. It has been used in jewelry for thousands of years. It enchants because of its color, rarity and luster (the appearance of a material’s surface in reflected light). Pure gold is soft, so it is typically alloyed with other metals. Karat is the term used to state gold’s fineness, which is based on 24 parts. Gold that is 75% pure—18K gold—is 18 parts gold and six parts of other metals to create an alloy. The most popular fineness in the U.S.—14K gold—is 14 parts gold and 10 parts of other metals.

*Tip: Metals with a higher amount of gold will have richer color, be heavier, softer (slightly more prone to dents and scratches) and more costly.

Rose gold has been a popular choice for many years. It was often used in engagement rings during the Retro era (1935 to the 1950s). It is usually made by alloying gold with copper and silver, which is what gives it its warm, pinkish tone. Companies closely guard their special blends.

White gold is made by alloying pure gold with white metals such as nickel or palladium among others. It is a beautiful and durable choice for engagement rings. White gold is usually plated with rhodium, a platinum group metal, to give it a whiter finish. This can wear away over time. White gold jewelry typically requires replating, or the slightly yellowish color of the white gold underneath may start to show through. This is easy and relatively inexpensive to do, however; simply ask your local jeweler for this service.

Platinum is a slightly grayish white metal that is extremely durable and corrosion resistant. Because platinum is soft in its pure state, it is typically alloyed with other platinum group metals such as iridium or ruthenium. Courtesy: Rahaminov

According to the U.S. Federal Trade Commission, only jewelry containing at least 95% platinum (5% alloys) can be marked “Platinum;” other platinum alloys are marked according to the Federal Trade Commission Guidelines. Platinum is generally more expensive than gold, but it is also hypoallergenic and more durable.

How Metal Color Affects Gemstone Color

White gold and platinum are good choices for diamonds graded in the colorless to near-colorless ranges–D through J on the GIA color scale—as they highlight the diamond’s colorlessness.

The color of the metal reflects throughout the diamond. Setting a colorless diamond in yellow prongs can cause it to look more yellowish in appearance. Gold and rose gold settings tend to benefit diamonds with lower color grades or colored diamonds or colored stones as they can help enhance the color of the gemstones. If you have a diamond with a distinctively yellow or brownish tint, a white gold or platinum setting might conversely emphasize the color of the stone due to contrast.

If you love the color of yellow gold or rose gold, use white gold or platinum prongs or bezels to set the diamonds and pair with yellow gold or rose gold bands. This way, the diamonds will appear more colorless while you get the style that you want.

5. Choose the setting

In jewelry, diamonds are held in place by settings. The setting has two jobs: to hold the diamond in place and to protect it from damage. Different settings offer different degrees of protection.

Here are two popular types of settings:

  1. Prong: A diamond is held in place with four to six prongs (narrow metal supports). The prongs can be rounded on top for a classic look or sharp (claw prongs) for an edgy, modern appearance. Six prongs can give a round brilliant diamond a more rounded look; it also holds the diamond securely. Four prongs can give a round diamond a slightly more square look, and they cover up slightly less of a diamond’s area. There are many variations to the prong setting and it can be used in a number of rings styles, such as solitaire, three-stone and more.

  1. Bezel: The bezel setting is one of the most protective styles. For this style, a thin metal strip is pushed or hammered all around the diamond to hold it in place. This means that the diamond cannot be viewed from the side, but it also means that there are no prongs that can snag on gloves (helpful for nurses) and that any corners are well-protected. It is an excellent choice for diamonds with sharp points that are more likely to chip, such as princess cut and marquise cut diamonds.

6. Consider side stones

Side stones are a dazzling way to dress up an engagement ring and make it look bigger. Popular choices include making the ring a three-stone ring, adding a halo, including channel, pavé or bead set diamonds along the shank of the ring, and adding colored gems or birthstones. If you want diamond side stones, choose those with 4Cs grades similar to that of the center stone. Having a similar color grade is especially important if you want the stones to match.

Three-Stone Ring: The three-stone ring, also known as the trinity or trilogy ring, symbolizes friendship, love, and fidelity, or past, present, and future. To add to its romantic connotation, you can incorporate birthstones for a personal touch.

Halo Setting: Adding melee diamonds around your center stone and on the shank can make the center stone look larger and add more sparkle to your engagement ring. Most rings have a single or double halo but there’s no limit to the number of halos you can add!

Cluster Setting: Cluster settings are a great way to maximize sparkle at a relatively affordable price. Smaller diamonds cost less than large ones and can be set in a way to create the illusion of a single larger diamond. Small diamonds also be arranged in unique designs.

7. Know Styles and Trends

What style of ring are you looking for—vintage, modern, timeless, Bohemian, romantic? Know your time periods and motifs or add personalized touches for a stand-out ring.

Vintage and Modern Vintage: Vintage styles are making a comeback, or perhaps they’ve simply never gone out of style! For an Edwardian style engagement ring, go for vintage motifs such as scrollwork, millgraining, and engraving. Many setting styles are rich with meaning. The toi et moi ring, French for “you and me,” has been popular for centuries. It features a ring with two gemstones representing the couple coming together. This motif was made famous by Napoleon who gifted his future-empress Josephine with a sapphire and diamond toi et moi ring.

If you’re looking for period jewelry, consider Art Deco style engagement rings and Art Nouveau style engagement rings. Also consider diamonds with older cut styles such as the rose cut or the Old Mine cut.

Heart Rings: Heart motifs have been popular since medieval times and have never gone out of style since. Not only do they symbolize love, heart shaped diamonds are typically more affordable than round brilliants. It is a unique option that will definitely make a ring stand out.

Bohemian Rings: Bohemian style rings play with unexpected gemstone shapes, setting styles and silhouettes, such as geometric diamond cuts, black diamonds, and rings with open shapes. Some are edgy; others have a more romantic vibe.

Stacked Engagement and Wedding Rings: Will your diamond engagement ring be worn alongside a wedding ring? Make sure that their silhouettes match and that the two rings fit together. A popular trend now is stacking multiple rings together with the engagement ring to complement it in design.

Custom Rings: Personalization makes rings feel unique and memorable. Consider a custom engagement ring for a one-of-a-kind ring that celebrates the special moments in your relationship.

8. Measure ring size

Once you’ve picked out a diamond and chosen a style for the ring, the next step is to measure the wearer’s ring size. The best way to do this is with a ring sizer, which is a series of plastic or metal rings in different sizes that you try on. Your jeweler will have a ring sizer and can help you find the perfect fit. If you want the ring-making process to be a surprise, try guessing ring size by borrowing a ring your fiancée or fiancé already owns. Trace the inner circle on a piece of paper. Or slide it down one of your own fingers and draw a line where it stops. A jeweler can help you to estimate the approximate ring size. Note that ring size varies from finger to finger, so using this method will only give you an approximation.

The good news is that most rings can easily be resized up or down by a size or two. Resizing more than that may be more difficult depending on the style of the ring. Solitaire rings are easy to resize, while rings with pavé or bead-set diamonds or other details on the band will require more work.

9. Pick a reputable jeweler

Since an engagement ring is a significant investment, you’ll want to buy it from a jeweler you can trust. Your jeweler should be armed with expert training, be open to questions and be able to explain how to buy a diamond in clear, simple language. Tip – start by looking for a jeweler who has earned a credential from a highly recognized and internationally accredited program, such as the GIA Graduate Gemologist (GG) or Applied Jewelry Professional (AJP) diploma programs. As your personal diamond-buying guide, an educated jeweler will not only explain the 4Cs of Diamond Quality, but will also be able to demonstrate the differences between apparently similar diamonds. They will encourage you to compare a number of diamonds that fall within your budget. The GIA Retailer Look Up can help you find local jewelers who carry GIA-graded diamonds or have GIA-trained staff.

10. Insist on a diamond grading report

A diamond grading report from an independent, scientific laboratory such as GIA is more than a document containing important information. Purchasing a diamond with a GIA report ensures that you know the identity and quality of your diamond. It tells you whether your diamond is natural and whether it has received any treatments. GIA Diamond Grading Reports are also used by appraisers to determine a diamond’s value if you want to insure your diamond engagement ring.

At GIA, we know diamonds. We created the 4Cs of diamond quality and the GIA International Diamond Grading System™ used worldwide for grading diamonds. Top museums and auction houses trust us to evaluate their finest treasures, and our reports are recognized internationally. We apply the same passion and precision we use in grading these world-famous diamonds to grading every diamond—including yours. Our expertise is reflected in a variety of diamond reports, ranging from the GIA Diamond Dossier to the GIA Diamond Origin Report.

Buying Guide: Colored Gemstone Engagement Rings

Colored gemstone engagement rings are hot. They’re showing up on royalty and celebrities alike. They’re beautiful. They’re unusual. And they can be a great value. Here’s what you need to know when you go shopping.

In this blog, we cover:

Why the trend in colored gemstone engagement rings

Colorful gemstone engagement rings are decorating the fingers of royals and other style makers, reviving a not-so-new trend for adding pops of color – and personality – to traditional colorless diamond engagement rings.

Some stylistas are achieving the color-me look with pink, yellow or blue diamonds, while others turn to the world of colored gemstones to find their splash of color.

More than 200 years ago, in 1796, Napoleon Bonaparte gave his future empress, Joséphine, a sapphire and diamond toi et moi (“you and me”) ring for their engagement.

Today, Kate Middleton, the Duchess of Cambridge, wears what is probably the most famous colored gemstone engagement ring. A beautiful creation that once belonged to Princess Diana, it boasts a 12 ct sapphire encircled by diamonds.

Kate’s recently engaged cousin by marriage, Princess Eugenie, daughter of Prince Andrew and Sarah Ferguson, opted for a slightly orangy pink padparadscha sapphire, surrounded by round brilliant cut diamonds. The style somewhat resembles the engagement ring her mother (the Duchess of York) received – a ruby with a halo of diamonds.

In the celebrity world, actress Jenny McCarthy wears a 10 ct yellow sapphire engagement ring framed by diamonds. Ashlee Simpson’s vintage-style ring features a marquise diamond surrounded by calibré cut rubies. Elizabeth Hurley sports a 9 ct blue sapphire framed by two trilliant cut diamonds in a classic design.

For these trendsetters – and many other brides – incorporating colored gemstones into an engagement ring offers myriad options to display their individual style and personality. It’s a look that’s both timeless and contemporary.

What’s great about colored gemstone engagement rings

There’s a lot to love about colored gemstone engagement rings. First, there’s the obvious: color. Explore the world of colored gems and you’ll find a rainbow, from the deep reds of ruby and blues of sapphire, to the grassy greens of tsavorite garnet and kaleidoscopic colors of spinel. There’s a gem for every hue imaginable.

Second, with colored gemstones you can add more depth of meaning to the engagement ring. For example, you could include your birthstone and your partner’s birthstone, alone or with diamonds. Colored gemstones also come with historic symbolism, and you could pick one that inspires you. Take sapphire – it has traditionally been associated with sincerity, truth and faithfulness.

You can also use colored gemstones to send secret messages. The Victorians turned this into an art form with acrostic jewelry – using the first letter of each gemstone to spell a word. For example, a diamond, emerald, amethyst and ruby set together would spell the word “dear.” Acrostic jewelry can also be designed to spell birthdays, private messages or a secret shared between you and your beloved.

Finally, there’s affordability. Colored gemstones are a great way to add size to an engagement ring. This is especially true if you look beyond rubies and sapphires toward gems that are less well known but equally as beautiful – and usually significantly less expensive. Examples include the pink beryl morganite, the many colors of spinel and tourmaline, or intense green, red or orange garnets.

Morganite engagement rings are recent favorites with brides-to-be – and for good reason. Pink has traditionally been the color of romance, and morganite ranges from pastel pink to purplish, yellowish or orangy pink. Similar hues are seen in pink diamonds, but you can have a large, attractive morganite for a small fraction of their cost.

Blue zircon, with its high dispersion, is often mistaken for blue diamonds. Yet while the cost of even a 1 ct blue diamond would be prohibitive for most buyers, a 3 or 4 ct blue zircon engagement ring is obtainable for far less than an average month’s salary.

Spinel and tourmaline are two other gems that offer a wide range of color options and great value. They occur in colors that are very similar to those of fine ruby or sapphire, but a top-quality 5 ct red tourmaline (rubellite) could be purchased for less than a third of the cost of a comparable 2 ct ruby – delivering more bling for your buck.

One of the most exciting, if less well known, colored gemstones seen in engagement rings is the green garnet known as tsavorite. More durable and often brighter than emerald, whose color it mimics, a fine tsavorite garnet is usually less expensive than its counterpart.

With so many different colored gemstones available, your challenge will be finding one that sets your heart aflame – and making sure the gem is tough enough for daily wear.

Durability and colored gemstone engagement rings

Durability is a major consideration when searching for an engagement ring gemstone. The gem you choose must withstand the bumps and bangs of daily wear, plus the effects of heat, light, household chemicals and low or high humidity. Different gemstones have different properties and, as a result, different tolerances to these stressors.

The Mohs scale ranks gem and mineral hardness in a range from 1 (least hard – talc) to 10 (hardest of all – diamond).

One aspect of gemstone durability is hardness. The Mohs scale ranks gem and mineral hardness on a scale of 1 (least hard – talc) to 10 (hardest of all – diamond). Ruby and sapphire rank 9, meaning they are able to resist scratching and abrasions. This makes them great choices for engagement rings that will see a lifetime of active wear. Although less hard, spinel (8), morganite (7.5–8), zircon (7.5), and tsavorite garnet and tourmaline (both 7–7.5) are considered durable enough for everyday wear provided care is exercised (no rock climbing!).

Toughness and stability are two additional factors that determine a gemstone’s durability.

Toughness indicates how well a gemstone resists breaking, chipping or cracking. The way the atoms of a gem bond together and the strength of these bonds determine gemstone toughness. Examples of not-so-tough gems are opal and tanzanite which, if set in rings, are best reserved for special occasions – not everyday wear.

Stability refers to how well a gemstone can withstand exposure to chemicals, light and changes in temperature or humidity. Extreme temperature changes can damage some gems like opal and tanzanite. Opals can crack or craze in low humidity or with exposure to heat. Citrine, amethyst and topaz may fade or change color from prolonged exposure to sunlight. Light and/or heat can also negatively affect most organic gems – such as pearls, coral and amber – as will exposure to household chemicals.

A 9.30 carat tanzanite center stone is surrounded by 1.18 carats of diamonds in this ring.

Tanzanite is a beautiful gem that calls for special occasions. At 6 to 7 on the Mohs scale with fair-to-poor toughness, it’s not ideal for an engagement ring that will see a lifetime of daily wear. Courtesy: Omi Privé

It’s important to note that many colored gemstones are routinely treated to improve their color and/or clarity. Designed to bring out the inherent beauty of a gem, many of these treatments are widely accepted in the gem trade. However, you should be aware that some treatments can also affect stability. As a result, your gem may require special care.

For example, treatments such as coating and fracture filling can be removed by heat and strong chemicals. Although emerald ranks 7.5–8 on the Mohs scale, it is not a tough gem and is often treated with oil and/or resin to improve clarity. This treatment also disguises fractures in the stone that can cause it to break if banged against a hard surface. If you have your heart set on a green gemstone engagement ring you plan to wear every day, you might want to consider a more durable tsavorite garnet instead, reserving emeralds for earrings or pendants. Garnets are rarely treated and have good toughness.

Other qualities to look for in colored gemstone engagement rings

Color is king

Like colorless diamonds, the quality of a colored gemstone is determined by a combination of the 4Cs: color, clarity, cut and carat weight. For colored gems, however, color is by far the most important factor. In some cases, such as whether a gem is called pink sapphire or ruby, or green beryl or emerald, the distinction may be made based on color alone. Clarity is important, but for most colored gems there is no universal grading system or set of standards to evaluate clarity. And cut may vary greatly from stone to stone. The goal is typically to maximize size and color – or, as in the case of fantasy cuts, to create a work of art.

There are, however, some important considerations to look for when assessing the quality of a colored gemstone in addition to the durability factors discussed above. Many gems show more than one color. This can be an asset in a bi-colored tourmaline – for the bride-to-be who wants a truly unique colored stone engagement ring.

In other gems, such as blue sapphire, colorless zones seen on close inspection may detract from the overall appearance of the gem. And while high clarity is desirable in most colored gems, as it is in diamonds, a few identifying inclusions in an inconspicuous area (such as the culet) may ensure that the colored gem is natural (not synthetic) and untreated.

Optical phenomena
Colored gemstones also offer the possibility of certain phenomena, such as chatoyancy (the cat’s-eye effect) and asterism (a star), that are not seen in diamonds. These phenomena are caused by the reflection of light off dense inclusions of minerals in gems cut as cabochons. Such phenomenal stones provide exciting design options for a colored gemstone engagement ring.

Where the gem comes from
For some gems, such as ruby and sapphire, country of origin may also play a significant role in determining value. For example, a ruby from Myanmar (“Burmese” ruby) can cost significantly more than a comparable ruby from another locality, such as Mozambique. Similarly, there is a premium for sapphires from Kashmir, due to both their distinctive “cornflower blue” color and their rarity: There has not been major production from this region for more than a century.

Who owned it before
Another important factor in determining price is historical provenance. An antique or vintage colored gemstone engagement ring may come with its own story, and that story may have value. In one of the most striking examples, when the Empress Josephine sapphire and diamond engagement ring mentioned above was offered at auction in 2013, the auction house estimated its value at $20,000 based largely on the gems alone. Ultimately, the winning bidder paid more than $1 million – a huge premium for the ring’s storied association with Napoleon Bonaparte and his first bride.

Quality and rarity drive value
Like diamonds, colored gems of high quality are rare, so buyers typically pay a premium for top-quality colored stones. Once you’ve decided on a gemstone for your engagement ring, it pays to comparison shop to understand its quality factors and how they affect value. You should also learn as much as you can about your gemstone of choice. GIA’s Gem Encyclopedia is a good place to start. It provides in-depth information for 29 of the most popular gems on the market. You’ll also find detailed buying guides for each gem describing the specific qualities to look for, the gem’s durability, common treatments and more.

Caring for colored gemstone engagement rings

After you’ve purchased your colored gemstone engagement ring, you’ll want to keep it like new. The right way to clean it will vary depending on the gem material you’ve chosen and whether or not it’s been treated. Usually, gentle cleaning solutions specially formulated for delicate gems – or just warm, soapy water and a soft cloth – are all you need. If you’re uncertain about the durability of your gem, avoid using ultrasonic cleaners and off-the-shelf cleaning solutions.

Setting styles for colored gemstone engagement rings

Engagement ring settings must secure the gems they hold as well as show them to their best advantage. Bezels, halos and other protective settings can play an important role in preventing the chipping or cracking of colored gemstones. But who said practical can’t also be beautiful? Settings serve as an essential design element, defining an engagement ring’s style and overall look. Settings let you introduce contrasts in color or harmonize them to get just the right amount of color pop in your ring. Consider these examples:

  • A three-stone engagement ring. A three-stone engagement ring is rich in symbolism: The gems represent yesterday, today and tomorrow. Wear it and you’ll proclaim that your love is eternal. The style has also withstood the test of time – three-stone diamond engagement rings date to at least the 17th century. Adding color with rubies, emeralds, sapphires and onyx to a white canvas of diamonds and platinum was popular in the Art Deco era.

  • A halo setting. This setting features a circle of gems surrounding the center stone. Diamond engagement rings with halo settings have been particularly popular these past several years because they’re beautiful, add sparkle and make the center stone look larger. The halo setting is also a favorite for colored gemstone engagement rings. You’ll often see the center stone providing a bold splash of color, while a circle of diamonds or colored stones adds sparkle and contrast – as well as protection for the gem they surround.

  • A bypass ring. Want an engagement ring that looks a bit different and has color? Consider the bypass ring – a style where the band overlaps, instead of completing the circle. Bypass rings were popular in the Victorian era. The sentiment behind these toi et moi rings has an undeniably romantic cachet.

Guide to Diamond Shapes for Engagement Rings

There are so many diamond shapes to choose from when shopping for an engagement ring: round, square, marquise and more. Here’s a guide to what makes each shape special to help you pick the perfect diamond shape for your engagement ring.

First, it’s important to know the difference between a diamond’s shape and its cut. It is common in the diamond marketplace to refer to diamond engagement ring shapes as “cuts.”  Shape describes a diamond’s basic outline when viewed face up (round, square, oval, etc.). Cut, or cutting style, refers to how the diamond’s facets are arranged. For example, the most common cutting style for diamond shapes is the brilliant cut with an arrangement of 57 or 58 facets designed to maximize sparkle. So when you find that perfect emerald cut diamond engagement ring, know that what you have is actually a square or rectangular shaped diamond engagement ring.

Some diamonds, most commonly square or rectangular shapes, are step cut. Emerald cut and Asscher cut diamonds are examples. The step cut has concentric rows of facets on the crown and pavilion for a more elegant look. However, not all square or rectangular diamonds are step cut; many are brilliant cut, like the radiant and princess cut diamond.

All diamond shapes other than round are called fancy shapes. Read on to learn more about these diamond shapes:

Round diamond shapes

What’s great about round diamond shapes

Round is the most popular of the diamond engagement ring shapes, and it holds this title because the round brilliant cut is designed to produce maximum brightness, fire and sparkle in a colorless diamond. The modern round brilliant cut diamond has a round girdle outline, 56 symmetrically placed triangular and kite-shaped facets, a table facet and an optional culet facet, for a total of 57 or 58 facets.

Lapidaries have been cutting round diamonds for centuries, but it wasn’t until the invention of the bruting machine in the early 1870s that a round diamond could be more easily made with a pleasing, symmetrical outline. The first of these was the old European cut diamond, a precursor to the modern round brilliant cut but with a higher crown and greater total depth than its modern counterpart. The old European cut is still a popular choice for brides wanting an antique look.

What to look for in round diamond shapes

Symmetry is key when shopping for a round diamond to feature in your engagement ring. And if the diamond is cut as a round brilliant, as most are, pay attention to its cut quality, or how well it interacts with light. Look for brightness (often called brilliance) – the internal and external reflections of white light. Fire – the flashes of color seen as you rock the diamond under the store’s spotlights. Sparkle – spots of light that flash when the diamond moves. And scintillation – a combination of sparkle and balanced patterns of bright and dark areas. Well-cut round diamonds are brighter with more fire and scintillation than poorly cut ones, even if they’re of equivalent colorclarity and carat weight.

Avoid diamonds with extremely thin or “knife-edge” girdles or with inclusions near the girdle, which make them more vulnerable to damage.

To be certain of the quality of the cut on your round brilliant diamond, buy one with a GIA diamond grading report, which will provide an objective assessment. Look for a cut grade of Excellent or Very Good.

Rectangular diamond shapes

What’s great about rectangular diamond shapes

Rectangular diamond shapes have a long history and a reputation for classic elegance in an engagement ring. The elongated shape can make a bride’s fingers look longer and more slender. Three of the most common rectangular diamond shapes are actually modified rectangles: the emerald cut, cushion cut and radiant cut.

Emerald cut: With its crisp, sophisticated lines, the emerald cut is the most popular of the step-cut diamonds. Its four longer sides have beveled corners with two, three or four concentric rows of facets, parallel to the girdle, on the crown and pavilion. An emerald cut diamond engagement ring is a perennial favorite with the stylish elite.

Cushion cut: Adorning the fingers of brides for centuries, the cushion cut diamond has curved sides and rounded corners. It typically has a high crown, small table, deep pavilion and large culet facet. Since the cushion cut retains more color face up than a brilliant cut, a cushion cut is well suited to colored diamonds. A cushion cut diamond will be a hit with a bride who favors an antique style for her engagement ring.

Radiant cut: One of the newest rectangular shaped diamonds is the radiant cut, a modified brilliant cut introduced in 1977. It boasts the fire of a round brilliant cut diamond in a rectangular or square shape with cropped corners.

What to look for in rectangular diamond shapes

As with all diamond shapes, symmetry is important for rectangular diamonds. Facets on opposite sides should be parallel to one another, corners should be cropped to identical size and the culet should be well centered.

Emerald cuts do not hide inclusions as well as brilliant cuts due to their long rectangular facets, so high clarity is important. Emerald cuts are also less scintillating due to the step cut style of faceting. Since lots of scintillation masks lower color grades, this type of facet pattern looks best on a diamond with higher colors on the GIA D-to-Z color scale. However, it can intensify color in a colored diamond.

For radiant cut diamonds, look for brightness, sparkle and scintillation, as you would for a round brilliant cut diamond. Clarity is less of a concern, as the modified brilliant cut faceting pattern can disguise inclusions that would be more visible in an emerald cut diamond.

Square diamond shapes

What’s great about square diamond shapes

Square diamond shapes in engagement rings are perfect for the woman with long, slender fingers who wants them to look shorter. They are also a statement of individuality for a bride who would appreciate a contemporary alternative to the classic round brilliant cut. Want a square shaped diamond in your engagement ring? In addition to the square versions of the cushion cut, emerald cut and radiant cut diamonds described above, consider the princess cut or Asscher cut.

Created in 1981, the princess cut diamond has a modified brilliant facet arrangement that gives it electrifying sparkle and scintillation. For a very different, but surprisingly modern look, the Asscher cut – first introduced in 1902 but since modified for greater brilliance – is similar to a square emerald cut but with larger step facets, a higher crown and a smaller table. Unlike the pointed corners of the princess cut, the corners of an Asscher cut are cropped, giving it the appearance of an octagon.

What to look for in square diamond shapes

Again, look for good symmetry. Facets should match on either side of an imaginary line drawn down the middle of the stone. Look for a balanced contrast of light and dark patterns in the table and other facets.

Fine princess and Asscher cut diamonds will not have a culet facet, which must be taken into consideration when mounting the stone. The culet is a safety facet that helps protect the point on the pavilion from chipping when the diamond is loose or if it is exposed in a setting. In addition, for the princess cut, it is important to choose a prong or bezel setting that protects the pointed corners.

As with emerald cut diamonds, the Asscher cut is most effective for diamonds that are colorless (D–F on the GIA color scale) or colored diamonds.

Marquise diamond shapes

What’s great about marquise diamond shapes

An attractive, elongated shape with a royal pedigree, the marquise (pronounced “mahr-keez”) was supposedly named for the Marquise de Pompadour, a mistress of King Louis XV, as its outline resembled the shape of her mouth. Because of its shape, a marquise diamond ring will look larger face up than a round diamond of the same weight. A marquise diamond engagement ring can also make the finger appear longer and more slender.

What to look for in marquise diamond shapes

Several factors must be considered when choosing a marquise diamond for your engagement ring. You want a marquise that is neither too long (and thus may sacrifice brightness and pattern) or too short (“stubby”) and thus loses the benefit of length to your bride’s finger. The points at either end should be sharp.

Note the regal gentility of this 0.91 ct marquise diamond and the two smaller marquise side stones. Courtesy: 1stdibs.com

Symmetry is extremely important for marquise diamonds. Both sides (wings) should have the same amount of curve, and the facets on one side of that imaginary line down the center of the diamond should match exactly the shape and size of the facets on the other side. Since the tips of a marquise diamond are where it is most vulnerable, it is not unusual for them to have slightly greater girdle thickness. If the marquise diamond is prong set, choose V-shaped prongs for the tips. A well-cut marquise will typically display a minimal to no bow-tie pattern.

Oval diamond shapes

What’s great about oval diamond shapes

Although a shape that is many hundreds of years old, the oval diamond has gained popularity for engagement rings in recent years because of its elegance and the fire it shows when cut in the brilliant faceting style. In addition, with its greater surface area, an oval diamond may appear larger than a round brilliant diamond of the same weight (and, like rectangular and marquise diamonds, can help elongate shorter fingers). One advantage over other fancy shapes is that the rounded edges make it less prone to chipping.

What to look for in oval diamond shapes

Pay attention to proportion. Longer oval diamonds are preferred by some, but they are not practical to cut so tend to be harder to find.

As with other fancy diamond shapes, symmetry is essential to ensuring beauty in an oval diamond. Again, placing an imaginary line down the length of the diamond and then across its center, the shape and faceting of the two halves should be identical.

Also look for a graceful outline and the size and nature of the bow-tie pattern. The bow tie on a well-cut oval diamond will be minimal or non-existent.

Pear diamond shapes

What’s great about pear diamond shapes

An irresistible blend of the marquise and round brilliant, the pear shaped diamond is a stylish choice among diamond shapes. Worn with the point toward the tip of the finger, its graceful, tapered shape can make the hand look slimmer and more elegant, perfect for an engagement ring.

What to look for in pear diamond shapes

Pear shaped diamonds come in a variety of proportions, so there are many options for choosing one that flatters the finger. Look closely at the wings on either side of the point to make sure they are symmetrical, with the rounded end a good semi-circle. Since the point is the weakest feature, look for (and avoid) inclusions in that area. If prong setting the diamond, use a V-shaped prong on the point for greater protection.

As with oval and marquise diamond shapes, the bow-tie pattern on the table should be minimal, or better yet, non-existent.

Heart diamond shapes

What’s great about heart diamond shapes

The heart shaped diamond is the essence of romance. It is also a very flattering style for larger fingers.

What to look for in heart diamond shapes

There are good reasons why this is one of the rarest of diamond shapes for engagement rings. A well-shaped heart requires a large diamond, at least one-half carat. In addition, inclusions tend to be more prominent in this shape, so you want a diamond that has good clarity. Symmetry is also key: The well-rounded lobes should match in size and shape, as well as faceting style, and the cleft between them (as well as the point) should be well defined.

Diamond Engagement Ring Setting: How Metal Affects Diamond Color Appearance

Selecting the right metal for your engagement ring setting is just as important as selecting the right diamond. The metal will not only define the ring’s style, but it can also play a big role in your diamond’s color appearance. Here’s how to choose wisely.

Gold, platinum and silver are the metals most often used in jewelry. Their allure, workability and durability make gold and platinum excellent choices for an engagement ring. For many people, choosing an engagement ring setting starts with a color and style preference. Some prefer the warmth of yellow gold or rose gold engagement rings; others opt for the coolness and classicism of white metals such as platinum or white gold for their engagement rings. Yet few people consider the effect that engagement ring’s metal color has on the most important feature of an engagement ring – the center stone, which is often a diamond.

The importance of diamond color and reflection

When choosing an engagement ring setting in white gold, rose gold, yellow gold, platinum or silver, consider these important things:

Your diamond’s color. Although many people think of gem-quality diamonds as colorless, truly colorless diamonds are actually very rare. Most diamonds used in jewelry and diamond engagement rings are nearly colorless with hints of yellow, brown or gray. In picking an engagement ring in yellow gold, white gold or other metal for your ring setting, you’ll need to know where your diamond is on the GIA D-to-Z Color Scale.

The fact that diamonds are highly reflective. The many facets of a standard round brilliant diamond and other diamond shapes act like tiny mirrors reflecting their surroundings, including the color of the band and the prongs holding the gem.

Knowing this, you can use the color of the metal in your engagement ring to highlight your diamond’s color or create a more harmonious appearance.

Once you’ve settled on whether you want your engagement ring design to highlight the main diamond or create a sense of harmony between the setting and the center stone, you’ll have many options to choose from. Remember, your jeweler is your best resource. She or he will understand the subtle nuances of diamond color and can make the best metal color recommendations to achieve the look you’re going for. Also, the best way to see a metal’s effect on diamond color appearance is to see the diamond and the engagement ring setting in person. In the meantime, though, here are some tried and true ideas to get you thinking.

Metals for diamonds graded D through J

All things being equal for diamonds on the D-to-Z scale, the less color the stone has the more valuable it is. Diamonds graded D-E-F on the GIA color scale are considered colorless, and a white metal—platinum or white-gold engagement ring setting is the ideal choice to emphasize their beauty. Diamonds graded G through J are in the near-colorless range, with an almost imperceptible hint of yellow. They, too, are good candidates for a platinum or white gold ring setting.

If you choose another color of metal or opt for a two-tone ring to create contrast, the prongs that hold the diamond should be a white metal like white gold or platinum. Yellow gold prongs could impart some yellow color to the diamond, making your colorless or near-colorless stone look like it has a different color grade.

Metals for diamonds graded M through Z

A diamond with a color grade of M or lower will likely have a noticeable yellow tint. A yellow gold band will accentuate the yellow in the diamond; a white band might make the diamond appear more colorless. Diamonds with a color grade of K or L are in something of a middle zone; you can use either yellow gold or white metal bands such as platinum or white gold, depending on the effect you want for your engagement ring setting.

Picking metals for fancy-color diamonds

Diamonds that fall outside the D-to-Z color range are called “fancy colors.” Selecting the right metal to accentuate these unique stones is key to delivering the radiance and allure of each engagement ring. Naturally occurring colors include bluebrownpink, yellow and green. These diamonds are evaluated less for brilliance or fire and more for color intensity. Depending on the hue, tone and saturation of the color, the GIA Colored Diamond Color Grading System assigns colored diamonds one of these color grades: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark and Fancy Deep. Generally, Fancy Vivid and Fancy Deep command the highest prices.

Metals for brown diamonds

Brown diamonds were once deemed unsuitable for jewelry. Then marketers in the 1980s gave them tantalizing names like champagne, cognac and chocolate, and brown diamonds developed their own niche.

Like yellowish diamonds, brown diamonds can be placed on a white gold or platinum engagement ring setting to highlight their color, or they can be placed in a yellow gold or rose gold engagement ring setting to complement their color. Even the metal used for prongs can either contrast or complement the diamond in the center.

Metals for yellow diamonds

Yellow diamonds were relatively rare until the discovery in the late 1860s of quantities of what today would be considered fancy yellows at several locations in South Africa. They are now found around the world. The presence of nitrogen gives them their color.

A platinum or white gold engagement ring can highlight the color of a yellow diamond, while a yellow gold ring will harmonize with the color of the yellow diamond.

Metals for pink diamonds

Pink diamonds are exceedingly rare. Historically, they have been found in Brazil’s alluvial workings and in Indian and African mines. Since the late 1980s, the Argyle mine in Australia has been the most important source of pink diamonds, but even here they are quite rare. According to Rio Tinto Ltd., the owner of the mine, “more than 800 million carats of rough diamonds have been produced from the Argyle Diamond Mine. Total carats of pink rough: less than 1% of total production.” Not surprisingly, pink diamonds are extremely expensive.

Since the color of pink diamonds is so prized, it is rare to see them set in a yellow gold engagement ring setting. A pink diamond is the star, and the white metal band is used to highlight its color.

Metals for blue diamonds

Blue diamonds are also extraordinarily rare and very expensive. India is their historic source, and it is believed that the 45.52 ct Hope Diamond, the 31.06 ct Wittelsbach-Graff and other famous blue diamonds originated there. Today, the Premier mine in South Africa, which opened in 1903, is considered the most significant source of blue diamonds. Nevertheless, at the end of the 20th century blue diamonds accounted for less than 0.1% of diamonds found there.

Like pink diamonds, they are almost always set in a platinum, white gold or silver engagement ring setting that highlights their color.

A beautiful engagement ring is the product of a number of choices that add up to a stunning creation. Knowing how to protect your diamond engagement ring setting is another important consideration.

Victorian Style Engagement Rings: How to Get the Look

Victorian style engagement rings evoke a romantic past. Flowers, hearts and acrostic messages are just a few of the motifs you can use to create a symbol of your love. Learn more about this captivating engagement ring style.

The Victorian era is named after Queen Victoria (1819–1901), who ruled Great Britain for almost 64 years, from June 20, 1837 until her death on May 1, 1901. For decades, the beloved monarch’s tastes influenced art, style and customs. A wreath of fragrant orange blossoms that she wore on her wedding day became the fashion of the time for British brides. The jewelry that she wore, which was featured in newspapers, was widely copied.

Queen Victoria’s marriage to Prince Albert lasted a brief 21 years. Their love was celebrated and idolized by an admiring public. After Albert’s untimely death from typhoid in 1861, Queen Victoria spent the rest of her life in mourning, but her love for Albert became the stuff of legend.

Queen Victoria’s jewelry collection included a serpent bracelet she wore to symbolize “the wisdom of the serpent” that she sought as the head of state, reset treasures from the Crown Jewels, a heart-shaped locket with strands of Prince Albert’s hair (worn after his passing), and a sapphire and diamond diadem. Particularly beloved were the jewels Albert gave her, often of his own design. His wedding gift was a sapphire and diamond brooch, which she wore proudly in her bridal portrait. Over the years that followed, in honor of the floral tiara she wore at her wedding, he gave her several pieces in the orange blossom theme.

Mourning jewelry, which she wore after Albert’s death, became the style across England. In addition to the black enamel, jet and onyx of mourning jewelry, diamonds continued to play an important part in Queen Victoria’s life. As a widow, she dressed herself in black silk and diamonds.

During Queen Victoria’s long reign, a number of revolutionary inventions reshaped society: anesthesia, the telegraph, the telephone, automobiles, bicycles, the electric bulb and railways. It was a time of comparative peace and prosperity for a growing middle class who could afford to purchase jewelry. In the late 1860s, the discovery of large quantities of diamonds in South Africa put a gem that was once reserved to the aristocracy and wealthy within the reach of many.

As Queen Victoria reigned for more than six decades, the period is rich in jewelry styles. Here are some motifs you can use in your one-of-a-kind Victorian style engagement ring.

Victorian Style Engagement Rings: Secret Messages

Victorians loved acrostic jewelry – using the first letter of gemstones to spell a word. For example, the word “Regard” was spelled by using a ruby, emerald, garnet, amethyst, ruby and diamond. Regard, Adore, Dear and Dearest were popular acrostic terms, as were birthday wishes. Acrostic jewelry was meant to send private messages known only to one’s beloved. That makes it perfect for your personally-designed custom Victorian style engagement ring or wedding band.

Victorian Style Engagement Rings: Love and the Serpent

The snake has been used as a symbol for millennia. Today the snake may have negative associations for many; however, during the Victorian era, the snake represented love, eternity and wisdom. Adding a snake motif to your custom Victorian style engagement ring and wedding band could be an edgy and eye-catching choice.

Victorian Style Engagement Rings: Flower Power

Victorians loved horticulture, built greenhouses to grow exotic plants and devoured books on the subject. They felt specific flowers had specific meanings: Tulips meant passion, bluebells represented kindness, myrtle stood for good luck and love in marriage, red roses symbolized love, and purple violets conveyed “thoughts occupied with love.” As a result, the giving of flowers often conveyed emotions that could not be spoken out loud. Now that you know the meaning of these blooms, you can add the appropriate flower or even a bouquet of flowers to your Victorian style engagement ring.

Victorian Style Engagement Rings: The Eternal Diamond

By the latter half of the 19th century, the discovery of diamonds in South Africa had put the dream of a diamond engagement ring within reach of the rising middle class. A gem that was once extremely rare was now being mined in sufficient quantity to fulfill the demands of a broad range of people.

The old mine cut, an early cushion-shaped brilliant cut with many proportion variations, was often used in jewelry during the early and mid-Victorian periods. It has 58 facets like most round brilliants, but it typically has a smaller table, larger culet and higher crown. Other characteristics include short lower half facets and a girdle that is very thin in places. As a result, an old mine cut diamond has a very distinctive look. Advances in diamond-cutting technology in the late 1800s allowed cutters to create round girdles. This led to the old European cut, precursor to today’s round brilliant cut, gaining popularity during the late Victorian period.

For centuries a plain gold band was a common choice for an engagement ring. By the Middle Ages, though, gem-set “betrothal rings” had become fashionable. In 1477, Archduke Maximilian of Austria gave Mary of Burgundy a diamond betrothal ring, one of the earliest on record. To bring more light (and, thus, brilliance and sparkle) to the faceted diamonds that were becoming increasingly popular, the Tiffany Setting (a six-prong setting) was introduced in 1886. A diamond solitaire is still an extremely popular choice for an engagement ring, and the use of an old mine (or similar) cut diamond will give your custom engagement ring the essence of Victorian style.

Victorian Style Engagement Rings: A Heart for Your Sweetheart

The image of a heart has long represented love, and it especially appealed to Victorians, who had a soft spot for things sentimental. Then as now, the motif is a popular means of expressing affection. A heart-shaped diamond – or any gemstone – is an easy way to get the look in your Victorian style engagement ring. Two pear-shaped stones coming together in a single heart send the same message in a very clever fashion.

Victorian Style Engagement Rings: Crossover Rings

A crossover ring wraps around the finger, with the ends of the band passing each other. The style was popular in the 1890s, and still remains so. It is also called a toi et moi ring (“you and me” in French). The two stones are said to symbolize the intertwining of two lives. Such a romantic notion would be a lovely design choice for your Victorian style engagement ring.

Radiant Cut Engagement Ring – A Brilliant Option

A radiant cut engagement ring is an irresistible combination: It has the fire of a round brilliant diamond and the aristocratic elegance of an emerald cut. Created in 1977, the radiant cut has been charming brides-to-be for decades.

A relative newcomer to the ranks of fancy-shaped diamonds, the radiant cut can be square or rectangular; notably, it has cropped corners and brilliant-cut facets. Diamonds with less-than-exceptional clarity can be good candidates for radiant cut engagement rings: In addition to giving the stone plenty of sparkle, this brilliant-cut faceting pattern disguises inclusions that would be more readily apparent in an emerald cut.

Buying a Radiant Cut Engagement Ring

Radiant cut diamonds have broad appeal. Elongated stones can create the effect of slenderizing fingers, while shorter styles can flatter even the most petite hands. To determine which proportions work best for you, we recommend trying on various options to find the perfect radiant cut engagement ring.

Important characteristics to look for in any radiant cut diamond are a well-centered culet, parallel sides and corners cropped to identical size.

The enchanting sparkle and alluring appearance of radiant cut diamonds makes them especially attractive as solitaires. And they don’t require extra embellishment to stand out from the crowd: Taste-making celebrities like Megan Fox sport the cut.

The radiant cut diamond also pairs well with side stones. Shapes with straight edges—like trilliants, or baguettes and other rectangular stones—are popular in radiant cut engagement rings because their linear silhouettes are complementary. And while you’ll often see radiant cut diamonds oriented north-to-south in engagement rings, the east-to-west orientation is gaining in popularity.

Engagement Ring Settings to Make Your Diamond Look Bigger

Engagement ring settings should be both beautiful and practical. A setting defines your ring style, adds drama to the diamond and protects it from loss or damage. The right setting and band can also make your diamond look bigger and even more sparkling.

If you’re looking to create an illusion of size, here are some tips for engagement ring settings that can make your diamond “grow.” But first, let’s start by debunking some dubious recommendations floating around the internet.

What Doesn’t Make a Diamond Look Bigger

Diamond shape and carat weight: While a diamond’s outline – round, rectangular, oval, pear, marquise — can have some influence on the overall perception of diamond size, the shape of a diamond alone does not guarantee the stone will look bigger. The same is true for diamond carat weight. Just because one diamond weighs more than another of the same shape doesn’t mean it will look bigger. Similarly, one diamond might look bigger than another of the same shape and weight, but may be less appealing overall. That’s because there might be many factors at play, especially those related to the quality of the diamond’s cut and how its weight is distributed.

A diamond’s shape – and even its carat weight – won’t guarantee a large-looking gem. Excessive bulge, shown here by the shaded areas on either side of the pavilion, adds to a diamond’s weight without contributing to the stone’s perceived size. Illustration: Peter Johnston/GIA

Here are some examples:

  • A diamond with shallow cut proportions may be physically wider and longer, but it will be far less appealing. That’s because a lot of the light that enters the crown of a shallow diamond might exit through the pavilion, making the diamond look dull and unattractive.
  • A shallow pavilion depth – less than 38 percent – can create a “fish eye” effect, seen as an unattractive gray ring under the table. (Pavilion depth is measured as the distance from the bottom of the girdle plane to the culet.) As above, the diamond may be physically wider and longer, but the stone will have a dull, flat look.

  • On marquise, pear and heart shaped diamonds, the sides near the points are called wings. If they’re too flat, they make the stone look too narrow. If they’re too rounded, they make it look short and stubby.

White metal band: A common misconception about engagement ring settings is that a white metal band can act like a mirror to reflect and amplify a diamond’s size. The logic seems sound until you consider that a rose gold or yellow gold band could serve as a dramatic counterpoint to the diamond, making it look bigger. So a white metal band is not a foolproof solution.

Colored gemstones: Colored accent stones provide dramatic contrast to a center stone, but do they make the diamond look larger? Not necessarily. One could convincingly argue that a colored stone would compete with a diamond, thus distracting the eye.

Slender prongs: A potentially troublesome myth about engagement ring settings is that the less a prong covers a diamond, the more of the gem that’s shown, so the bigger it will look. While this may be true technically, it is not advisable. Prongs serve an essential function: they hold a diamond securely in place. Skimp on the necessary size and number of prongs, and you risk losing the diamond.

What Does Make a Diamond Look Bigger

Here are some engagement ring settings to consider if you’re looking to boost the appearance of your diamond’s size.

Illusion setting: During the Great Depression of the 1930s, when few could afford large diamonds, jewelers sometimes set a diamond in a head made of a fluted white metal. The shiny metal was made with ripples, so the whole head looked like the diamond it reflected. This setting was so successful in delivering an illusion of size that it’s still used today.

  • TIP: The purpose of the illusion setting is to make a near-colorless diamond look larger, and white metal is required to achieve this particular effect. If the diamond is yellow in color, then a yellow gold illusion setting is a better choice.
  • TIP: Diamonds smaller than 0.50 carat (ct) are good candidates for illusion engagement ring settings. You’d probably want to showcase a diamond 0.50 ct or larger on its own, instead of relying on the illusion setting to work its optical magic.

Cluster setting: This engagement ring setting places several small diamonds of similar size next to each other. This technique maximizes sparkle and gives the illusion of a single diamond that is much larger in size (and more costly) than the melee diamonds used to make it.

  • TIP: Diamonds of the same or similar color grades work best in a cluster setting. Diamond manufacturers know this, and match color grades when producing these kinds of rings. So you won’t have to worry about selecting the many smaller diamonds that will be part of your cluster setting.
  • TIP: The more metal surrounding a stone, the more it is protected. Cluster settings have lots of metal. So your diamonds will be better safeguarded against damage.

Halo setting: When a ring of smaller diamonds is artfully placed around a center stone, the center stone can appear to be the size of the halo.

  • TIP: Engagement ring manufacturers select the melee that makes the halo, so you won’t have to worry about picking the many small diamonds that will go into the engagement ring setting.
  • TIP: A diamond center stone weighing 0.50 ct or more works best in this kind of setting because the melee in the halo will enhance it. You probably wouldn’t want to use a smaller diamond, since it would be too close in size to the melee. That combination would probably look like a pavé set ring with one diamond (the center stone) somewhat larger than the rest.
  • TIP: The prongs on halo diamonds tend to wear out faster. Should you go with this style, be sure to have your ring routinely checked by your jeweler.

Pavé setting: To achieve this popular technique, many diamonds 0.20 ct or smaller are set into tapered holes in a metal surface, nestled close to the melee stones next to them. Pavé creates an appearance of uninterrupted diamonds in the band, which can make the center stone look larger.

  • TIP: Pavé set diamonds in engagement ring settings are typically very secure, as the diamonds are set into metal. However, should a diamond fall out, it is more difficult for a bench jeweler to replace it.
  • TIP: Avoid engagement ring settings with pavé set diamonds on the bottom of the shank. This area of the ring is exposed to a lot of friction, so the diamonds are more easily lost or damaged.

Bezel setting: In this setting style, a band of metal surrounds the diamond’s girdle. As a result, the diamond’s circumference may appear to be larger. Bezel engagement ring settings also afford extra protection against accidental bangs and bumps.

  • TIP: The bezel setting is generally used for round and oval diamonds. It is more difficult to create a bezel setting for other shapes, such as square and marquise diamonds.
  • TIP: Like rock climbing? Playing lacrosse? Vigorous exercise? The bezel setting protects the center stone, so it is a great choice for active people.
  • TIP: A bezel setting could deaden the brightness of a poorly cut diamond.

Invisible setting: For this technique, small diamonds are cut with grooved pavilions and then slipped into a thin wire framework. This eliminates the need for prongs and allows the gems to be set against each other. The result is that the entire diamond is visible, and groups of diamonds can look like one large gem.

  • TIP: There is a drawback. Should a diamond in an invisible setting be damaged, it is extremely difficult to repair or replace it. So Invisible diamond engagement ring settings are probably not a good idea for physically active individuals.

More Tips to Make Your Diamond Look Bigger

Choose a thin ring shank or band: Here’s a way to trick the eye. A thin band can make a diamond look larger. Similarly, a thick band might overshadow the diamond.

Add side stones to your engagement ring setting: This is a great way to add sparkle and size to an engagement ring – and the options are endless. You could add a diamond baguette on each side of the center stone. You could pick colored stones to create contrast. You could use different colored metals around the side stones.

Unlike the melee used for pavé and halo settings, you may have the opportunity to choose the side stones. If you are uncomfortable making the choice, read our advice on choosing engagement ring side stones to get you started. If you have any questions, ask your jeweler for help, he/she will have a trained eye.

And last, but certainly by no means least: keep your diamond clean. While a clean diamond won’t look bigger, per se, it will display that signature sparkle that telegraphs “diamond” across a crowded room – and isn’t that what it’s all about?

Speaking of diamond sparkle, here are some tips and tricks to get the most sparkle out of your diamond engagement ring.
