More about the Masterclass

Become a diamond polisher for a day, guided by one of the Royal Coster master polishers. Your experience begins with a private tour of the Diamond Museum. Then, you take a seat at the polishing table to transform a rough diamond into a brilliant one. This exclusive 4-hour workshop is designed for one or two people. You receive personal coaching and a unique insight into true craftsmanship. At the end, your polished diamond is yours to take home, complete with an official certificate. You can also choose to have it set in a custom piece of jewelry. 

The masterclass includes refreshments, a goodie bag and a certificate of completion.
