The radiant cut diamond is a beautifully symmetrical cut, with a shimmering 70 facets, that was designed by Henry Grossbard in the late 1970s. He created a cutting technique that combined the best elements of emerald and round diamond shapes, allowing radiant diamonds to exhibit incredible brilliance and fire.

​

He was part of Radiant Cut Diamond Company, who released the first radiant diamond in ’77. Grossbard’s creation changed the way rectangular diamonds were viewed and developed. His was the first to have such an intricate facet pattern on both the pavilion & the crown of the stone. Every other rectangular-shaped diamond before this release had fewer facets, less attention to the finer details, and shone less brilliantly than Grossbard’s version. In 2002, RCDC launched its own specific brand: the “original radiant cut.”

Though radiant diamond cuts are known for their rectangular, emerald-like shape, they can also have a more square-like shape resembling a cushion cut diamond. However, there is no mistaking the difference between these two cuts as the radiant cut diamond has noticeably many more facets and significant sparkle.

A radiant cut is, basically, a hybrid stone that is generally square or rectangular but with slightly cropped corners that contribute to its eye-catching sparkle.
