His was the first to have such an intricate facet pattern on the pavilion of the stone as well as the crown. Grossbard’s creation changed the way rectangular diamonds were viewed and developed.

He was part of Radiant Cut Diamond Company, who released the first radiant diamond in ’77. Henry Grossbard created the very first radiant cut diamond in the late 1970s. The modern radiant diamond itself is less than 40 years old. (In case you're thinking of jumping on that sapphire and diamond engagement ring trend.) This diamond shape also tend to be a very popular choice for fancy colored diamonds because they capture more rough diamond color than other cuts. The difference simply comes down to their length to width ratio. But radiant diamonds are also available in a square shape. The rectangular radiant cut diamond is an excellent option for buyers who like the emerald cut shape, but want something with the brilliance of a round. Radiant cut diamonds are in the gemstone cut group known as hybrids, which speaks to how its characteristics can be seem as combinations of some of the other stone shapes, including the cut's beveled corners. Simply put, these are the square diamond of the common round, brilliant gems. Radiant cut diamonds are often called the rectangular modified brilliant diamond. Overall you could say that the radiant diamond combines some of the most beloved traits of other popular diamond shapes. The faceting of a radiant cut gives it a fiery look compared to a princess cut, while maintaining soft, cut corners. Trimmed corners give this loose diamond shape versatility to shine in all kinds of jewelry, especially engagement rings. The radiant cut diamond is a beautifully symmetrical, non-traditional cut, the radiant cut combines the brilliance of a round and the purity of an emerald cut.
