The day the Amsterdam diamond cutter Moses Elias Coster moved into factory premises at Waterlooplein in 1840, Coster Diamonds was born. During that time, diamonds were still cut by machines literally powered by horses. But not for long. Thanks to Moses' pioneering spirit, Coster Diamonds was the first diamond cutting factory in the Netherlands to introduce steam as the source of power.
Coster was not only ahead of his time, he was also a huge perfectionist. Only the very best was good enough, and soon it rained domestic and foreign orders. One of these represented an invitation by the English Queen Victoria to re-cut the Koh-i-Noor. As a result of this immense challenge, Coster was officially recognized 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 and until today – more than 70 years later – the heritage of Mozes Coster has been kept alive in three stately premises, beautifully situated between the Rijksmuseum and the Van Gogh Museum.
