Discover the World of Diamonds at Royal Coster’s Private Tour
If you’re curious about what makes a diamond truly special beyond its sparkle, a visit to Royal Coster Diamonds might just be a highlight of your Amsterdam trip. This private tour offers an intimate peek behind the scenes of the world’s oldest diamond-polishing factory, where centuries of craftsmanship meet modern expertise. While it’s not a full-blown museum experience, it’s a solid choice for anyone interested in the finer details of gem cutting and history.
What really makes this experience stand out are two things: first, the personalized guidance you receive, making the tour feel more like a friendly chat than a formal presentation. Second, the chance to watch skilled polishers and goldsmiths at work — something you don’t get to see every day unless you’re a professional yourself. On the flip side, a possible downside is that the overall experience can sometimes lean more toward a sales pitch, especially if you’re expecting a purely educational tour.
This tour is well-suited for travelers who love jewelry, are interested in luxury crafts, or simply want a meaningful activity that’s different from the usual sightseeing. It’s also good for those who appreciate quality over quantity — a compact, quality experience that won’t eat up your whole day. If you’re okay with a visit that combines history, craftsmanship, and a touch of commercial flair, you’ll find this quite engaging.

The Experience: What You Can Expect

Starting at Royal Coster Diamonds, the tour is relatively short, lasting around 50 minutes to an hour. You meet your private guide at the factory’s location on Paulus Potterstraat, right in the heart of Amsterdam. From the moment you arrive, you’ll be immersed in an atmosphere that feels both historical and contemporary.
Your guide will kick things off with a warm introduction to the factory’s long history — it’s the oldest diamond-polishing factory in the world, and it’s been involved with jewels for monarchs globally. This background sets a tone of prestige and craftsmanship that’s hard to match. Expect to hear tales about royal orders and iconic diamonds that have passed through this workshop.
Once inside, the real magic happens. You’ll get a close-up look at handy artisans as they work on diamonds, transforming rough stones into sparkling masterpieces. The guide will explain the intricate process of polishing and cutting, emphasizing that this process takes millions of years from the initial discovery to the final polish. You’ll learn how diamonds are evaluated using the 4 C’s, which deepens your appreciation for what makes each gem unique.
Viewing the collection is another highlight, especially the chance to see Europe’s largest collection of unset diamonds. The highlight here is the Royal 201 diamond, a patented cut that’s renowned for its brilliance. The guide will tell you why it’s considered the best diamond cut, adding a layer of exclusivity and expertise.
The tour doesn’t just stop at the process. You’ll also get a chance to see jewelry displays—from exquisite pieces to more affordable options—which gives you a broader perspective on how diamonds and jewelry are styled and valued.

Authentic Reviews and Real Opinions
Many visitors mention how the private aspect of the tour enhances the experience. One reviewer noted, “It made it more special for our mother,” emphasizing that the personalized approach really pays off. The guide’s knowledgeable and charming manner was also appreciated, making the visit engaging and informative.
However, not all reviews are glowing. Some travelers felt the tour leaned more toward sales, with one saying, “Nothing on the diamond making process you couldn’t Google,” and a feeling that the visit was more about pushing jewelry sales than education. That said, if you’re someone who appreciates seeing craftsmanship firsthand and doesn’t mind a sales element, this shouldn’t be a dealbreaker.
The value for money is often praised. For just over $26, you get a guided, private experience plus a sparkling goody bag — a small but nice touch that makes the experience feel more special and memorable. Reviewers also appreciated the good flow and timing, with most feeling they had enough time to appreciate the craftsmanship without feeling rushed.

Considerations and Caveats
While many agree this is a worthwhile short experience, it’s worth noting that some visitors felt it was more sales-oriented than educational. If your main goal is to learn about diamond manufacturing without the pressure to buy, you might find the latter part of the tour less engaging.
Accessibility is limited — the tour is not designed for those with walking difficulties, as the factory involves some standing and moving around. Also, transportation isn’t included, so plan your route accordingly.
Finally, timing is important — most travelers book their slot about a month in advance, which indicates it’s popular but also that you should plan ahead if you want to secure a private spot.
Who Should Consider This Tour?
This private diamond tour is ideal for jewelry enthusiasts or anyone interested in luxury crafts. It’s also suited for those wanting a personalized experience that combines history, craftsmanship, and a touch of exclusivity. If you’re intrigued by royal jewels or the process of turning raw stones into works of art, you’ll find this tour compelling.
On the other hand, if you’re expecting a museum-like, purely educational experience free from commercial elements, you might be disappointed. It’s also not suited for those with mobility issues or looking for a full-day activity — this is a quick, focused visit.
