We took the tour not knowing it was coming as part of bus tour. Interesting divided opinion from those on same bus tour. Bottom line is we enjoyed it because of a genuine interest in the stones. If you are not then we can understand the number that didn't enjoy. One thing to know is that there is absolutely no... More

My husband and i left half way through the tour because it was a little mundane. You can buy diamonds here if you're mega rich, if not then they serve free tea and coffee in the shop! If your interested in the craftsmanship of diamond making then great, if not then there is plenty more things to do in Amsterdam.

The only reason we popped in here was because our Sightseeing boat/bus tour stopped outside. You are supposed to be able to see them making the diamonds but out of the 10 or so seats only 2-3 were occupied and there was no explanation or unable to see/know what they were doing. The rest of the place was cabinets full... More

It was a free tour which we really enjoyed. Personally I have never seen a €40000 diamond so I found this tour absolutely great! The staff were friendly and you could see the staff making the diamonds. They taught me a lot about the diamonds and if I could have afforded to buy something I would have! There was free... More

Well worth a visit. Very interesting finding out about how they cut the diamonds and different cuts and grades. Its a free tour and they could show you more, but at the end of the day they want to sell you some. Its not a hard sell of course and there always seems to be someone that is going to... More

I did thoroughly enjoy this experience. I was alone, which was fine and I was made to feel totally comfortable. I had pre booked in my tour, which was a nice feeling to have it confirmed. I had turned up at the Gassan Diamonds shop in Dam Square but they helpfully pointed me in the right direction. After a free,... More

We visited with 3 other couples on our trip to Amsterdam. The visit was free but we were all prepared for the hard sell. The surprise was, there wasn't any hard sell, just an interesting little tour with information on how they cut the diamonds. Then out came trays of jewellery that we could try and drool over for a...

Diamonds tour isn't really a tour, you see a couple of people working on the diamonds, polishing i think, unsure, then you go to another room & sit with a lady for 15 mins, who explains about the the different cuts, colours and clarities and shows you samples, tells you prices & then thats it There is a huge watch...
