Coster Diamonds is one of the city’s oldest operating diamond firms founded back in 1840.It was the first factory in Holland to use steam powered machines and has been entrusted with the polishing of many famous diamonds. Prince Albert of England, for example, commissioned Coster Diamonds with the re-polishing of the world famous “Koh-I-Nohr” or “Mountain of Light”, a blue-white diamond which is part of England’s crown jewels. Coster also polished the Star of the South, a lilac coloured stone which is considered to be one of the most valuable stones ever. During your visit you will also see the Lucullan, a unique diamond (181.15 carats): the largest unpolished gem in the world.

Each year approximately 350.000 visitors come to see our craftsmen work. The free guided tours are given in more than 26 languages by a highly trained staff who will explain in detail how diamonds are polished. After the tour, visitors can browse around in our spacious showrooms. Here one sees an extensive collection of loose and set diamonds and one of the largest collections of diamonds weighing over 1 carat.

Coster Diamonds has the most ideal location. What could be more perfect than having your establishment located between the Rijksmuseum and the Vincent van Gogh Museum? Just opposite of our main entrance is the parking garage for coaches. Parking is free of charge during your visit at Coster.
