For the highest quality diamonds, luxury watches and jewelry, visit GASSAN Diamonds! GASSAN has played a crucial role in the history of Amsterdam as diamond City. It was established by Samuel Gassan in 1945, just after the Second World War, as a business specializing in the import and export of raw and cut diamonds. Today GASSAN Diamonds is located in a beautifully restored diamond factory built in 1879. Here, various tours are organized for circa 350.000 visitors a year. Here, visitors can view the diamond polishers at their craft, while multilingual guides explain how to turn rough diamonds into dazzling brilliants. In addition, GASSAN is also an official dealer of Rolex watches, and is very proud of its own unique patented cut: the GASSAN 121.
