Nemesis International have partnered with the luxury jeweler de GRISOGONO, establishing themselves as the source for the best polished diamonds, providing the brand with the resources to produce the finest quality jewelry.

The Constellation’s outstanding size and clarity allows de GRISOGONO an exclusive opportunity in its cutting and polishing process providing the brand with the unique option to bring a jeweler’s perspective into the cutting process. This is contrasted to the more traditional process where jewelers were restricted to acquiring polished stones that already existed in the market. The partnership allows Fawaz Gruosi, Founder and Executive Board Member of de GRISOGONO to decide on how best to cut this stone to customize one of the most astonishing jewelry pieces ever created.
