Our Legacy

The Royal Legacy

Royals and diamonds have always been closely connected. Back in the days emperors and rulers used jewellery and diamonds as an expression of their power and position. These days royals wear diamonds mainly as beautiful accessories to official occasions. Often we see that jewellery worn by royals passes on from generation to generation in remembrance of their ancestors.

Our Legacy

Coster Diamonds’ royal clientele

In the second half of the 19th century, the British Royal House wasn’t the only name of importance trusting Royal Coster Diamonds with their jewellery. Among the royals that graced us with their visit were Napoleon Bonaparte, Prince Victor Emanuel and Empress Sissi, names probably more known to the public than Queen Victoria. Travelling at the time was an expensive luxury that was done seldom, which makes this royal list even more impressive.

Our Legacy

Royal Coster Diamonds and the Dutch Royals

Royal Coster Diamonds and the Dutch Royals have been closely related pretty much from the early years of our existence. The day King Willem III and his son The prince of Oranje set foot in our establishment in 1862, Royal Coster could proudly call themselves purveyor of jewellery to the Dutch royal household. An absolute highlight in that eventful history has been the polishing of 275 diamonds used in a diamond watch for Queen Juliana’s 50th birthday.
