Gassan Dam Square
Exclusive collection of top brand watches, diamonds and jewelry.
The family company Gassan Diamonds has the largest jewelery store of the Netherlands, located in a beautiful shop at Dam Square. Since 2017 they even have an official Rolx Boutique at Gassan Dam Square! However, Gassan Diamonds is still mainly focussed on the diamond grinding process, which is done in the diamond factory at the Uilenburgerstraat in Amsterdam. The headquarter of Gassan Diamonds is also located at the diamond factory. Besides the grinding of diamonds they are also specialists in golden jewelery and watches. For over 4 centuries craftmanship and tradition are the most important values at Gassan Diamonds.
