Breakfast at Coster

Breakfast at Coster

This year, Royal Coster Diamonds celebrates its 180th anniversary. But there is an extra reason for a party. Exactly 50 years ago we settled on Paulus Potterstraat 2, on the Museum Square in Amsterdam. That is why we organize something unique from 1 July 2020, especially for you. We introduce: Breakfast at Coster.

Breakfast at Coster is an initiative in which we invite you for a special experience at Royal Coster Diamonds. On the website, you can sign up for a champagne breakfast, lunch, or high tea. In addition to this breakfast, this lunch or high tea, you receive a private tour of our polishing factory, the oldest diamond polishing company in the world. You learn from our diamond experts how to distinguish a real diamond from an imitation one. Above all, you leave with a nice and well-filled goodie bag.
