    Gassan Story

    The worldwide patented diamond cut Gassan 121, developed by Gassan, is 10 years old! In 2005 this unique diamond shape was introduced during the Millionaire Fair in Amsterdam RAI.

    For more than 400 years perfecting the art of diamond cutters craft. When family company Gassan Diamonds continues this tradition and we are proud that the stunning Gassan 121 diamond shape, with one hundred twenty one facet this year celebrates its tenth anniversary. After years of research by Steve Bierman is eventually designed a new breathtaking diamond polishing method with 121 facets that result reflects optimally. In comparison with the conventional round brilliant cut shape, the Gassan 121, 16 extra facets on the top and 48 extra facets on the bottom. This creates an ultimate glare, in other words perfect beauty.

    According to a report from the WTOCD (part of the High Council of Diamonds in Antwerp) the additional facets enhance the contrast between the dark and light areas in the diamond causing the Gassan 121 has a spectacular look. This Gassan Diamonds also adds a fifth "C" to the value of the four 'C's, namely the' C 'of Confidence. The "C" stands for quality and authenticity of the cut. In the girdle of the Gassan 121 is the cut of name lasered. This cut has Gassan Diamonds also a worldwide patent.
