The Amsterdam diamond cutter Moses Elias Coster moved into factory premises at Waterlooplein in 1840, and Coster Diamonds was born. During that time, diamonds were still cut by machines literally powered by horses. Thanks to Moses' pioneering spirit, Coster Diamonds was the first diamond cutting factory in the Netherlands to introduce steam as the source of power.
In addition to being ahead of his time, Coster was also an incredible perfectionist. Only the very best was good enough, and it soon rained orders from Dutch and foreign customers. One of these represented an invitation by Queen Victoria to re-cut the Koh-i-Noor. This immense challenge established Coster as a master diamond cutter.
In 1970 the old diamond factory had to make way for the construction of the underground. Coster Diamonds moved to its current location at the Paulus Potterstraat. In three grand mansions, beautifully situated between the Rijksmuseum and the Van Gogh Museum, the heritage of Moses Coster is being done proud.
