Henry Grossbard was the inventor of the Radiant Cut,[1] a diamond cut similar to the Barrion but with different faceting; he was also the founder of RCDC Corp, marketing the original radiant cut.
Grossbard emigrated to the U.S. from Austria during World War II, and apprenticed with a diamantaire. He later became a master diamond cutter before inventing the Radiant Cut in 1976.
Grossbard died in 2005 in a hit and run accident, while walking his dog on Passover. The killer was never found.
Grossbard's son, Stanley Grossbard, assumed responsibilities for RCDC Corp. following Grossbard's death.[2] Stanley Grossbard is married to Hoboken Mayor Dawn Zimmer.[3] [4]
