How De Grisogono transformed one of the largest, purest diamonds ever mined

In a remarkable journey from mine to masterpiece, de GRISOGONO reveals the Creation I necklace featuring a 163.41 carat emerald-cut diamond, the largest of its kind in the world.

Since it first saw the light of day, this huge, billions-of-years-old diamond has been on an 18-month voyage, during which it was transformed from a 404.20-carat rough into a 163.41-carat emerald-cut D Flawless Type IIA diamond, set into a suitably magnificent necklace designed by Fawaz Gruosi, founder and creative director of de GRISOGONO. Christened The Art of de GRISOGONO Creation I and revealed in Hong Kong today, the jewel starts its world tour in a build up to an auction of the necklace by Christie’s in Geneva on 14 November at the Hotel des Bergues.

The 163.41-carat diamond is blessed with a trilogy of wonders. Not only is it a remarkable size and the enviable top-rank D colour, it is also a Type IIa diamond free from nitrogen, giving it exceptional clarity and limpid qualities.

The 163.41-carat diamond can be removed and set into future creations, to be determined by the new owner. In charge of auctioning Creation I, Rahul Kadakia, International Head of Christie’s Jewels, commented: “Over our 251-year history, Christie’s has had the privilege of handling the world’s rarest and most historic diamonds. The sensational 163.41 carat perfect diamond suspended from an elegant emerald and diamond necklace propels de GRISOGONO into a class of their own.”
