Over the centuries Amsterdam has built an excellent and well-deserved reputation for the high quality of its diamond polishing and cutting. In 1586 the very first diamond polisher was registered in Amsterdam. Since that date the polishing skills have been honed and passed on to subsequent generations. The world renowned Amsterdam Cut was perfected by the Amsterdam diamond cutters. So it is not without reason that world famous stones such as the Koh-I-Noor and the Cullinan were cut and polished in Amsterdam.

Amsterdam has over 400 years of history in diamonds, becoming the largest diamond city in the world. At Gassan Diamonds the rough stones are still transformed into beautiful sparkling diamonds every single day. Experience Amsterdam City of Diamonds - visit Gassan Diamonds.

The Amsterdam Cut is a brilliant cut diamond. The Amsterdam Cut received that name because the diamond polishers in Amsterdam had been producing the most sparkling diamonds possible for centuries. The knowledge required for this incredibly many-sided trade of diamond cutting and polishing has been passed on from generation to generation. The diamond polishers at both Gassan Diamonds and the Amsterdam Diamond Center are very successful in cutting Amsterdam Cut diamonds.
