Amsterdam City of Diamonds Foundation

The history of Amsterdam Diamond City begins in the 16th century and continues to date.

The Dutch capital still houses a number of diamond-cutting companies and diamond traders with – in some cases – worldwide fame.
GASSAN Diamonds and Royal Coster Diamonds are the two largest diamond polishing companies in Amsterdam.

Every year they receive a total of almost 1 million tourists from home and abroad, all interested in the craft of diamond cutting.

In order to keep Amsterdam as a City of Diamonds on the map worldwide, both companies set up the Amsterdam City of
Diamonds Foundation for joint promotional purposes.
