Amsterdam, diamond city

Amsterdam has been famous for its diamonds for more than 425 years, and GASSAN Diamonds is an important part of that history. It was established in 1945, just after the end of the Second World War, by Samuel Gassan, as a business specialising in the import and export of raw and cut diamonds. Today, the business is located in a monumental building on Uilenburg island in the centre of Amsterdam.

GASSAN 121

GASSAN’S diamond cutters have been working to create the perfect, brilliantly cut diamond for decades. This cut originally had 57 facets, but the cutters have since developed a unique, patented cut that has no less than 121 facets: the GASSAN 121. The increased number of facets gives the diamond even more brilliance.
