For over 400 years diamond polishers have perfected the art of giving maximum life to the brilliant-cut diamond. At Gassan Diamonds this tradition is being continued and the company is proud to introduce a breathtaking cut which has been patented worldwide: Gassan 121, which has 121 facets. In 2012 more than 377,000 visitors toured Gassan’s magnificent diamond factory and in 2013 Gassan was declared the best family business in the Netherlands by the Family Enterprise Foundation in partnership with KPMG. Visitors can view the diamond polishers practising their craft, while multilingual guides explain where diamonds are found and how rough diamonds are turned into dazzling brilliants.
