Frequently Asked Questions

What Is a Radiant Cut Diamond?

The radiant cut diamond revolutionized the jewelry world by fusing the brilliance of a round brilliant cut with the sophisticated contours of a rectangular or square shape.

This unique cut was introduced in the late 1970s by master cutter Henry Grossbard. Unlike traditional cuts, the radiant boasts a complex arrangement of 70 facets across its crown and pavilion, resulting in exceptional fire and sparkle[7]. Its signature beveled (trimmed) corners enhance both elegance and durability, giving the stone a chic and modern allure[4][8].

Radiant cut diamonds are popular in both engagement rings and fashion jewelry because they:

Reflect light brilliantly due to intricate faceting[1][7].
Can be cut in square or rectangular proportions, suiting various design preferences.
Appear larger than other cuts of the same carat due to the elongated diagonal[7].

Radiant Cut Diamond vs. Other Popular Diamond Shapes

The radiant cut stands apart for its blend of maximum brilliance and unique silhouette.

Feature	Radiant Cut	Emerald Cut	Princess Cut	Round Brilliant
Faceting	Brilliant (70 facets)	Step	Brilliant (57-76)	Brilliant (58)
Light Performance	High brilliance/fire	Emphasizes clarity	Very bright, geometric	Most brilliant
Shape	Rectangular/square, beveled corners	Rectangular, step corners	Square with sharp corners	Round
Durability	Beveled corners for chip resistance	Vulnerable corners	Vulnerable corners	No corners
Conceals Inclusions	Yes	No	Moderate	Yes
Face-up Size	Appears larger	Appears smaller	True to carat	True to carat

Radiant vs. Emerald Cut: While both have a similar external silhouette, radiant cuts feature brilliant-style faceting that produces vivid sparkle, unlike the understated, mirror-like flash of the emerald cut[1].
Radiant vs. Princess Cut: Both are “brilliant” faceted for sparkle, but radiant cuts have cropped corners for added durability, whereas princess cuts have sharp corners, making them prone to chipping[4][7].

Benefits of Choosing a Radiant Cut Diamond Ring

Opting for a radiant cut diamond ring offers a host of advantages—both aesthetic and practical.

Maximum Brilliance: The cut’s 70 facets channel light for exceptional sparkle, making it second only to the round brilliant in fire and radiance[7].
Larger Appearance: The elongated shape and faceting can make the diamond look larger for its carat weight, maximizing visual impact[7].
Durability for Daily Wear: With beveled corners, radiant cuts are less likely to chip, ideal for active lifestyles or daily engagement ring use[7].
Versatility: The balanced symmetry suits both classic and contemporary ring designs, flattering all hand shapes.
Concealment of Inclusions: The faceting style helps disguise minor imperfections, allowing for more flexibility when selecting clarity grades[1].
