    Very interesting visit! You can see the whole process, from rock to diamond, this was really amazing

    I am EXTREMELY DISAPPOINTED!!!
    We were in a group and we were supposed to have a full explanation about diamonds in a room and then have a glance of the recent collection products.
    But… the diamonds for the explanations didn’t arrive on time so the lady (who reallllly wanted to sell her jewels) started showing the products. We waited and waited… the tube with the diamonds for the explanation finally arrived but the lady really meant to sell her products and didn’t care explaining… and we ended up with a sale but no explanations at all which was the reason we visited the place!

    I personally had the chance to meet the loveliest person, Edwin, who explained to me a little about diamond shaping and how he worked. Thank you Edwin for making the visit worth it!

    First class service and a really informative tour from Isa. The history of the company is fascinating.

    It like a simple jewelry. Not much to see. There is no museum, no demonstration of the process of creating diamonds.

    An OK tour to learn a little about diamonds. Good that it was included in the cost of our hop on hop off tour as separate, it would be worth it in my view. Maybe if you are from Africa You may want to avoid, Diamonds are mainly from Africa.

    If you have an hour to kill, it's not too shabby. Great gift store here with actually unique stuff that also provides free coffee as well. The free tour is two parts, which together are less than an hour.

    It was an amazing experience there. Something new to learn. The guide was polite, nice and very well trained. And the tour is absolutely free. Do not miss this one in Amsterdam. :)

    The free tour is nice a bit short but you get some understanding of diamonds after they do try to sell to you.

    This diamond factory is the best diamond factory in Amsterdam. Tours are for free and very interesting. Before the second world war, this diamond factory was the biggest in Europe. Recommendable visit in Amsterdam

    Place to learn how they prepare the diamonds for the sales. But it's more a place to buy diamonds and not to learn the history of diamonds. Visit more commercial than effective learning. People who would like to know how they calculate the prices of diamonds will be delighted. Great collection of Rolex.
