Few things in nature are absolutely perfect. This is also true with diamonds. As touched on in the first part of the clarity series, diamonds have internal features called inclusions and surface irregularities called blemishes. Together, inclusions and blemishes make up a diamond’s clarity characteristic. (more…)
Diamond clarity is one of the four quality factors (the 4Cs) that describe and determine the value of a diamond. By definition, clarity means “a gemstone’s relative freedom from inclusions and blemishes.” These two terms are locational- blemishes are found on the outside of the gem and inclusions are located on the inside. Both of these clarity characteristics can dim the brilliance of a diamond, though some are so minute that they are invisible to the naked eye. (more…)
Hailing from the olivine group of minerals, the peridot is a mysterious and thought-provoking gem.

Perhaps a special piece of diamond jewelry has been passed down to you. It may be a ring or a pendant set with a beautiful gem. Because this item did not come from a jeweler or gemologist, you really have no way of knowing anything about the diamond’s color, clarity, cut or carat weight – those factors that determine quality, and help you decide whether the diamond is worth resetting or leaving it as it came.

Few things catch the eye like the ruby birthstone. This July birthstone has a color which can be described as a deep, pure, vivid red. Ruby, a variety of the mineral corundum (which also includes sapphires), is as historically captivating as it is beautiful.
In the ancient language of Sanskrit, ruby is called ratnaraj or “king of precious stones” for its rarity, hardness (second only to diamond), beauty, and for its seemingly mystical powers. (more…)
Often when picturing a diamond, we envision the classic colorless gem depicted in films, showcased in engagement rings, or displayed with other popular jewelry in glass cases. A colorless diamond is the clear, classic diamond we envision. Many “colorless” diamonds possess very subtle hints of yellow or brown, colors that can affect the value of the stone. But diamonds come in colors that extend beyond the D-to-Z color scale. And when the color of the stone is strong enough, the diamond becomes known as a “fancy-color diamond.” (more…)
When it comes to diamonds, most consumers tend to use the words “cut” and “shape” interchangeably. But for diamond professionals, there is a big difference. Diamond Shape refers to the outline of the stone (pear, oval, round, etc.). Diamond cut refers to a stone’s facet arrangement. So a shape can be faceted in a variety of ways, or cutting styles.
