During the Ambacht in Beeld Festival, one of the master diamond polishers from GASSAN Diamonds will give an exclusive one-on-one masterclass in which you will polish your own diamond together.

Polishing rough diamonds is a craft that has been practised in Amsterdam for centuries. Diamond is the hardest material on Earth and can only be worked using another diamond. Using a diamond polishing wheel, the diamond polisher transforms rough crystals into the most dazzling gemstones.

GASSAN Diamonds is a renowned family business in Amsterdam specialising in diamonds, jewellery and watches. Founded in 1945 by Samuel Gassan, the company has grown into a leading player in the diamond industry, with a strong focus on craftsmanship and quality.
