Coster diamonds was founded in 1840 and in the 175 years of its existence many royalty from all over the world visited Coster to see the most beautiful royal diamonds and the craftsman who make them.

CEO Kees Noomen: ‘companies can be considered for the royal title if they are at least 100 years old, are solid and reliable and are leaders in their field, preferably internationally.
