Discover distinctive events and have a special experience with Gassan

When visiting the historic Gassan factory in Amsterdam, dedicated staff supervise your party and welcome you with a hot drink and pastry (possibly showing your own logo). After this reception, a welcoming speech by one of the Marketing & Sales staff or possibly by the chief executive officer (subject to availability) follows. You’ll also receive a presentation on the history of the former steam-driven diamond factory before starting the tour, which explains how a rough diamond is polished to a dazzling brilliance. This programme lasts approximately one hour.


Additionally, Gassan offer a number of workshops, which provide greater insight into the distinctive features of the diamond business. Each workshop lasts approximately 20 minutes. Below is an explanation of the workshops.

• Showroom – You are given a detailed explanation in terms of determining the quality of a diamond, based on the C 4 system (carat, colour, clarity, cut). Guests are shown loose polished diamonds of different qualities. During the explanation in the showroom, your guests can use the jewellery cleaning service. This costs €5 per person (based on 4 pieces of jewellery per person).

• Laboratory – A demonstration of how Gassan Diamonds makes certificates using a special computer system. You can also view a real diamond under the microscope and check it for any impurities.

• Atelier – In the atelier, a goldsmith will explain what the various activities are and will give your guests a peek behind the scenes. There is also time for questions, which will be answered in detail.

• Watch lecture – For a group with a maximum of 50 people, a watch expert will give a special lecture about Haute Horlogerie.
