The Radiant Cut first appeared in 1977 as the culmination of 30 years research by Henry Grossbard, a native of Austria who became a master diamond cutter in New York.

Refer to the table below to see how we grade Radiant Shape diamonds. These take into account factors such as table and depth percentage, polish and symmetry, and length to width ratio. We’ve developed our own criteria to provide consistent cut grading for all the Radiant Shape diamonds we offer. Instead, it’s down to individual retailers to evaluate the quality of the cut for this shapes. This allows light to enter the diamond from many angles resulting in reflections with a many-layered effect.īecause of its high number of facets, a Radiant Cut diamond is more forgiving of flaws and weaknesses than our other rectangular shape, the Emerald Cut giving you the flexibility to drop a cut or clarity grade in favour of better colour or carat weight.Ĭurrently, there aren't any universally accepted standards for grading the cut of Radiant Shape diamonds so certifying laboratories don’t do it. The Princess Cut’s contrasting linear reflections complement its straight edges and sharp corners whereas in a Radiant Cut, which was designed by superimposing a round brilliant cut over a rectangular outline, the reflections are circular in nature. It’s a common misconception that a Radiant Cut is simply a Princess Cut with the corners cut off. On GIA grading reports it is often referred to as a “cut-cornered, rectangular (or square), modified brilliant”. However, bear in mind colour may be slightly intensified in the corners so we recommend a G colour grade or higher.Ī Radiant Cut diamond usually has 70 facets - 25 on the crown, 8 on the girdle, and 37 on the pavilion. We Sayįancy shaped diamonds with low colour grades offer exceptional value. The Radiant Cut is sumptuousness with a capital $. As an engagement ring, there is perhaps no shape that looks more extravagant or lavish.

Often rectangular but also popular as a square, the Radiant Cut diamond offers a uniquely different stone to those willing to see past the popularity of the Princess Cut. Its tightly patterned facets and truncated corners form a luxurious diamond pillow with sparkle enough to rival the Round Brilliant. This is a stone that oozes glamour: think Fred and Ginger, Greta Garbo, and Marilyn Monroe.
