Gassan Diamonds was founded by Samuel Gassan in 1945. He established the company’s offices at the Amsterdam Diamond Exchange on the Weesperplein in Amsterdam.
Nowadays Gassan has 500 employees. Several international shops and a head office in the diamond factory on Nieuwe Uilenburgerstraat in Amsterdam. The historic diamond factory used to be powered by steam. 2011 has been a turning point for Gassan, since Benno Leeser became the sole shareholder in the Gassan holding on 1 November. A clear branding strategy for the company was also developed in that year. Gassan is proud off its duty-free shops at Amsterdam Schiphol Airport and carry its brand name since April 2011. The Amsterdam Diamond Centre was transformed into a sophisticated Gassan flagship store in signature Gassan style – with international appeal, yet retaining the intimacy associated with a family company.
On 8 December 2011, Gassan launched the most recent Gassan jewelry collections at the Millionaire Fair: Gassan Junior, Special Moments, and the Haute Joaillerie collection with its proprietary Gassan 121 cut diamond.
