Royal Coster Diamonds, a brief history

Royal Coster Diamonds has been around for a long time, dating back all the way to 1840. That year diamond cutter Moses Elias Coster founded Royal Coster Diamonds in a factory near the Waterloo Square, located in the heart of Amsterdam. A lot has happened since then:

  • In 1848 Martin Coster successed his father. He often visited Paris and Antwerp in order to put Royal Coster Diamonds on the map abroad.
