A Royal Experience

Diamonds can be bought at any jeweler around the world. So why is Royal Coster Diamonds the most renowned diamond supplier for Royal families around the world for more than 178 years? We believe the reason for this is a combination of unparallelled craftsmanship and trust.

With our new Royal Experience we offer a new tour where you learn even more about our rich heritage.

Learn why Queen Victoria, Empress Sisi and King Rama V of Siam not only trusted us with their diamonds but took the time to travel all the way to Amsterdam to witness with their own eyes how we crafted the most sparkling diamond jewelry.
