HOUSE of GASSAN offers a Luxury Shopping Experience with a historic character, intended for the consumer looking for a luxury (personalized) purchase of emotional value for an important event in his or her life.

GASSAN differentiates itself from other department stores by creating an authentic experience for diamonds, (customized) jewelry and watches.  As such, the historic building on Nieuwe Uilenburgerstraat exudes craftsmanship. This is a unique feature; GASSAN polishes and cuts diamonds in-house. An ultimate experience and one that we offer at HOUSE of GASSAN.

House of GASSAN is the largest jeweler in the Netherlands with jewelry and watch brands like Tudor, IWC, Jaeger-LeCoultre, Longines, Messika, Chopard and many other brands like our own GASSAN brands:
