Each purchase at GASSAN is a gift. For this reason, every product is packed in a luxury gift box and comes in a luxurious paper GASSAN bag. The gift pack consists of blue or beige wrapping paper, depending on the article, with a matching GASSAN ribbon.

We are proud to use the exclusive logo giftwrapping of the majority of the brands we represent and our staff has been trained to follow their specific guidelines. For example, a Rolex watch comes with a Rolex box and a piece of jewelry of Chopard comes with a Chopard packing.

Car & courtesy service
Upon request, we arrange that guests of our partner hotels will be picked up by our chauffeur and taken to any GASSAN store. Our drivers also deliver packages and gifts at hotels if clients are not able to take or collect their purchases themselves.
GASSAN Diamonds has a private parking for visitors in front of the building.

Each product bought at GASSAN is accompanied by an international warranty card. In order to fully enjoy the jewelry or watch bought, we advise our clients in the most complete way on how to take good care of the items. GASSAN offers a two year guaranty, however we recommend having the jewelry checked by a (local) jeweler at least once a year on signs of wear and/or stones that may be loose. In addition, the jewelry will be cleaned professionally and at the same time it may also be worthwhile to have it polished.

Watches are warranted for two years from the date of purchase. This warranty is only valid if the warranty card has been filled out. It covers manufacturing defects only. Work performed by an unauthorized watchmaker will render this warranty null and void. The warranty card must always accompany any request for warranty service.
