Royal Coster Diamonds
During the tour, your personal guide explains everything you want to know about the mystical world of diamonds. He or she will tell you about the origins of the diamonds and the process a diamond goes through. This diamond process takes millions of years. Learn how to evaluate a diamond with the 4 C's (carat, cut, clarity, color) of diamond valuation. There is so much more to know and appreciate about a diamond than just the sparkle. You will be surprised. Besides seeing amazing diamond jewelry and Europe's largest collection of unset diamonds, you will also see the Royal 201 diamond. This is Royal Coster's own patented diamond cut and known to be the best diamond in the world. A regular brilliant has 57 facets, while this unique diamond cut has no less than 201 facets. These extra facets cause to make the light reflect even more within the diamond. This creates a sparkling effect that is no match for any other diamond shape in the world.

Less a factory , more a high end jewelry store where the very knowledgeable and friendly staff try to gauge your interest in buying one if their beautiful gems . I wouldn’t pay for a tour as they are free .

Be prepared to be sold diamonds. This is not a tour. This is a sham. This Trip Advisor company will ruin TA fine reputation quickly.

We were made to feel very welcome by all the staff. Staff were very accommodating as we had booked our tour for 1.30pm and they managed to get us a tour guide although we were several hours early. Simon was very informative and knowledgeable and witty. He made us feel like royalty and we had complimentary coffees and treats... the diamond displays were exquisite. This was a once in a lifetime experience and would highly recommend. The hostess , from Ukraine. was very helpful and friendly organising our early tour. Coster certainly have their customer service down to a fine art. Very enjoyable

Rosa was an amazing tour guide! She walked us through the diamond polishing area, showed us different diamonds, and went through the different characteristics of diamonds. She was so knowledgeable and fun throughout this experience and we learned a lot from her. Highly recommend!

The check in process was unclear, and an employee seemed unbothered that were there and simply told us to head into the next room. We were then invited a join a tour by another employee that happened to be starting, so we joined. However it became clear that this wasn’t what we had booked for, with the tour lasting only 30 mins not the hour we had booked for. What annoyed me was that whilst we were listening into the group tour, our private guide noticed we were there but did not bother to pull us aside and let us continue with the short version. It was still interesting to understand the process of polishing and cutting diamonds.

I was surprised that we had a private tour. It made it more special for our mother. The staff was both charming and knowledgeable.

I got in contact with Royal Coster Diamonds since one of my hobbies is collecting loose diamonds and gemstones. I know a lot about diamonds, the diamond trade, diamond cutting etc. On advice I booked the Royal Experience Private Tour. After the tour I spend even more time in the different showrooms with the friendly, competent and hospitable staff memember. I highly recommend this tour. The gift bag you will receive is really brilliant.

A care of 10 from the first moment. We had a Reservation for a guided tour and we were attended individually and not as a group. Great everything. They gave us a nice discount on the purchase and we left very happy. They also invited us to a drink during the visit and after the purchase, to champagne to celebrate. Thank you so much!

We visited out of pure interest, not to buy any diamonds. We were shown around by a lovely knowledgeable gentleman who was not only too happy to answer all of our (sometimes silly) questions but provided us with a thorough explanation of the diamond cutting process. It was fascinating to see all the diamonds whilst learning why their own cut is considered one of the best in the world. There were opportunities to select and buy diamonds and have them made into jewellery if you wished and when I’m next looking for a special item of jewellery I would definitely return.

Was greeted by someone who hardly spoke English. Didn't want to show us anything about the diamond making process. Was whisked away to a showroom. When we started to walk out saying this whole thing was a sham and we came to see the diamond making process, a lovely woman intervened and chased the idiot that had been assigned to us away. She salvaged the visit and gave a very nice tour and a presentation of very beautiful cut diamonds. She also gave us a bag of token gifts but it wasn't worth $50.
