A free tour with a hot drink at the end - from a machine...... Interest talk on how they grade and cut the diamonds. But it was a selling operation, followed by the only exit through their shop.

Great to see how actually the diamonds are cut and polished. But this tour is more like a selling tour. So if you are planning to purchase diamonds then you should visit their factory. Otherwise nothing very special.

This was a very professional tour with excellent information about the cutting of diamonds and how diamonds are valuated. If you are interested in diamonds then this is the place to visit. Some great bargains too. Very professional and knowledgeable.

The most interesting part of the tour was how they cut the diamonds, but I found it to be more about selling than anything else. This place I would consider a tourist trap and would not recommend it as a place to visit.

The Gassan Tour happens to be a stop on the "Hop on Hop off" Canal tour. It is included in other tours as well. Our tour guide was quite knowledgeable. The tour took about an hour and we witnessed a diamond cutter and were shown the various cuts, colors and shapes. The second area demonstrated what contributed to the value... More

This is a very busy but well organised diamond centre which offers to make jewellery normally within half an hour. There are many pre-made in the shop. The girls are fantastic guides and know all about diamonds. I was never a real enthusiast before my visit but would like to own a few diamonds now!

I went on the tour because it was free with the bus tour, and I love diamonds. Thank goodness I didn't pay for this tour!. A lady shows you some TINY diamonds at astronomical prices and we are supposed to ohhh and ahh over them, not happening! Most of it was boring, and, like I said I am a diamond... More

We bought one ring, and had another resized. As the task meant we were at risk of being in a rush for our flight, they kindly booked and paid for our taxi to the airport. When the ring was done, it was not quite as expected so they gave full cash refund, and were incredibly helpful. The other ring was... More

Only took about 30 minutes but it was really interesting to see how diamonds are cut & styled. We learnt about cut, colour & clarity. I think the easiest way to get to the museum is via the red hop on hop off boat.
