The Original
Radiant Cut
Invented with the goal of maximizing the beauty of each diamond, only the Original Radiant Cut is cut to Mr. Grossbard's exacting standards and artistic ideals. Before Mr. Grossbard conceived of the Radiant Cut, all diamonds with straight edges, like the emerald cut, were faceted with long rectangular facets. This cutting style, called the "step cut" results in a diamond with a glassy appearance. Diamonds with rounded edges, like round diamonds, pear shapes, ovals, and marquises, are faceted with triangular facets. By creating a technique to combine these two cutting styles, Mr. Grossbard was able to release the natural brilliance of a straight edged diamond.

Henry circa 1958
Henry Grossbard equated his development of the Radiant Cut to a sculptor's artistic design process. "An experienced craftsman can look into the rough stone and see the finished diamond," he often explained. As an artist he sought to create the most exquisite square and rectangular shaped diamonds. "I didn't create the radiant for weight retention," Mr. Grossbard said, "I did it to create a beautiful diamond."
