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.
Due to the quantity and freshness of the products, it is necessary to reserve at least one (working) day in advance. You can indicate how many people you come with and whether you have certain allergies and/or dietary requirements. Due to the current corona measures, there is only limited availability. We, therefore, recommend that you book as soon as possible. There are three options for Breakfast at Coster:
During our Luxury Shopping Experience, you will be completely pampered. Choosing a diamond is a special occasion. While enjoying a glass of champagne, one of our diamond consultants will take you through all the ins and outs that come with choosing the perfect diamond.
This Masterclass Deluxe is given exclusively by our best diamond polishers. They give you an in-depth Masterclass that ends – if you do it correctly – with an official certificate.
If you are looking for a sparkling exciting addition to any event; the Champagne Surprise is perfect for you. Every guest gets a glass of champagne with a little sparkling stone inside. But is it a real diamond or a fake one?
Our diamond polishers will check each stone closely with a diamond loupe and reveal who is the lucky winner.
