“Stress the make!!!” – Israel Starck (Founder & President of the I. Starck Co., Inc.)

At its birth, the Radiant Cut Diamond was very slow to take off; the brilliantly skilled, Master Diamond Cutter Henry Grossbard (z”l) knew how to cut the significant and extraordinary Radiant Cut, but was not familiar with the art of marketing a stone, to generate demand.  When most risk-averse investors failed to recognizing the revolutionary engineering and awesome potential for the Radiant Cut Diamond, the I. Starck Co., Inc. succeeded to envisage the Radiant Cut Diamond’s award winning future.

I. Starck Co., Inc. was instrumental in naming and introducing to the U.S. and international diamond consumers market, a new diamond cut.  In use since 1976, the name Radiant Cut Diamond has been universally accepted, and has gained full recognition to date as a most coveted member of the diverse diamond cut family.  The Radiant Cut Diamond was, in fact, so radically new and different, combining the classic elegance of the traditional emerald shape with the fiery brilliance of the round brilliant cut.

Following an explosion in popularity for the Radiant Cut Diamond that the I. Starck Co. helped create, diamond cutters around the world began producing stones, some of them near imitations, based on a foundation identical to that of the Radiant Cut Diamond, such as: Princess cut, Starburst cut, Tycoon cut, Tiffany’s Lucida cut, etc. 
I. Starck Co. Inc. shaped not just the Radiant Cut consumer market, because when considering the demand and interest these “imitations” generate, one can argue that the I. Starck Co. Inc. has revolutionized the diamond consumer market worldwide!

Since 1976, the I. Starck Co., Inc. has maintained its position in the global diamond market as the leading purveyor of the Radiant Cut Diamond, and we will persist as the leading purveyor for many years to come!
