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.

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.
