For generations, the diamond cutters at GASSAN Diamonds in Amsterdam have been working to perfect the brilliant cut. With the GASSAN 121 diamond, they have finally succeeded. Whereas a brilliant cut derives its symmetry from its 57 facets, our diamond cutters have succeeded in adding another 16 facets to the top and another 48 facets to the bottom of the diamond, taking the total to 121 facets: a cut that produces an unrivaled, perfectly shimmering diamond.

Cut with unique brilliance

The GASSAN 121 diamond is known for its beautiful brilliance, thanks to its extra facets. The 121-faceted diamond was introduced in 2005 and given the appropriate name GASSAN 121. This special cut is patented worldwide, which means that GASSAN is the only company in the world that can cut diamonds this way. The name of the cut is also lasered into every single 121 diamond. Because of their unique brilliance, these diamonds have now become the most popular range in our entire diamond collection.

From 4 to 5 C's

The 4 C’s are very famous in the world of diamonds, representing cut, carat, clarity and colour. The sum of these four properties will determine the value of a diamond. With its special new cut, however, GASSAN Diamonds has added a fifth C, for confidence. The spectacular appearance of the GASSAN 121, which it owes to its 64 extra facets between the dark and light parts of the diamond, requires great perseverance and confidence from the diamond cutters.
