  • Our history

    The Gassan Story

    Gassan Diamonds was established in October 1945 by Samuel Gassan. The diamond merchant was mainly involved in the cutting and polishing of diamonds and the import and export of both raw and cut diamonds, gemstones and jewellery. Gassan Diamonds was wholesaler and retailer at the same time. Tourists came to Amsterdam from all corners of the world to see diamond cutters at work.

    Samuel Gassan noticed that by giving tourists information about diamonds and the craft of diamond cutting, they would buy diamonds. Gassan Diamonds has been hosting tourists since 1955, and to this day, this formula appears to be extremely successful. Gassan Diamonds achieved a record number of visitors in 2013, more than 400,000 people. At Gassan Diamonds, we speak 26 different languages, so that everyone can enjoy a unique guided tour. It's also fun for Dutch people to book the tour.

    The unique thing about Gassan Diamonds is that you can create your own jewellery. You choose a setting and a cut and your customised jewellery can be ready within 30 minutes. The unique Gassan 121 diamond in particular is often a preferred choice for this.

  • Our diamond cut

    Gassan 121, the perfect cut.

    For generations the diamond cutters at Gassan Diamonds have optimised the stunning brilliance of a brilliant cut diamond.

    They worked on the symmetry of each of the 57 facets with only one goal in mind: perfect beauty. Of course the next generations of diamond cutters will still be working on the same goal.
