Royal Coster Diamonds is the oldest diamond polishing factory in the world. Since our establishment in 1840, Royals from all over the world came to Amsterdam to see our Amsterdam craftsmanship. We’ve welcomed visitors like Empress Sisi, the Viceroy of China, King Rama V, Prince Napoleon and many, many more.
Today this Royal experience is within your reach. Visit our four monumental 19th century villa's and see how we create beauty that lasts for centuries. We give private guided tours during which your guide vividly tells you about the history of these precious stones and how Amsterdam became the City of Diamonds. You dive into our rich legacy that is filled with Royal Stories. Your guide explains how diamonds are formed and polished, while you see our polishers and goldsmiths up close. You can take a picture of yourself behind a real diamond polishing table and you learn how to analyze a diamond and why some diamonds sparkle more than others. At the end of the tour, you receive a nice goody bag you can use to value your or your family’s diamonds and diamond jewelry.
Duration approx. 20 - 60 minutes | €12,50 per person

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.
