Gassan is a family-owned diamond company located in Amsterdam, Noord-Holland.

The company offers hands-on and guided tours including the Diamond Polishing Experience Tour, See Diamonds In Style Tour, Gassan Diamond Experience Tour and the Diamond & Champagne Tour.
Each experience highlights the workshop process and the unique GASSAN 121 cut.
