Gassan Diamonds

Factory in Nieuwmarkt, Plantage & the Eastern Islands

See diamond cutters and polishers in action at this workshop. You'll have a one-hour guided tour (no charge), which will prime you on assessing diamonds, then land you up in the shop with a chance to own your own sparklers, at a price.

The factory sits on Uilenburg, one of the rectangular islands reclaimed in the 1580s during a sudden influx of Sephardic Jews from Spain and Portugal. In the 1880s Gassan became the first diamond factory to use steam power.
