Coster Diamonds

Coster Diamonds, established in 1840, is one of the oldest diamond factories in Amsterdam. It’s located around the National Museum area. The factory’s reputation stems from cutting the 186-karat diamond named Koh-i-Noor into a 108-karat diamond which is mounted in the Crown of the British Queen during the 1930s. Tourists can enjoy free guide service here, watch the craftsman cut the diamonds and also learn about the process of diamond production.
