Royal Coster

With almost 200 years of history, we are experts in cutting diamonds. We know diamonds. We have made jewellery for Prince Napoleon, for Empress Sisi and in 1852 the craftsmen of Royal Coster were chosen by Queen Victoria to re-polish the largest diamond in the world; the Koh-I-Noor (Mountain of light).
