The Art of de GRISOGONO, Creation I, is revealed, a journey from mine to masterpiece of a one-of-a-kind High Jewellery necklace featuring the largest 163.41 carat D-Colour Flawless diamond ever to come to auction.

Peerless diamonds, unparalleled craftsmanship, superlative jewels and a unique partnership for historical gems, as Christie’s and de GRISOGONO set a new standard for sublime luxury. A dazzling new chapter in which historically signifcant diamonds in the most spectacular settings take centre stage.

de GRISOGONO proudly presents an asymmetric necklace starring the 163.41-carat diamond as its centrepiece. The magnifcent gem is framed to the left by 18 emerald-cut diamonds; a nd to the right by two rows of pear-shaped emeralds set against a darkened gold background creating the Maison’s signature chiaroscuro efect.



François Curiel said: "In my long career, I have had the privilege of handling many exceptional stones, some of them truly phenomenal, a few absolutely spell binding. The magnifcence of this 163.41 carat D Flawless diamond by de Grisogono has got to be one of the highlights of my 48 years in the business.

And how would one describe a dream like this? Already a miracle at birth, it was a 404.20 carat rough of immaculate colour and clarity. It is then transformed by an elite international team of cutters, designers and craftsmen into a stunning necklace set with emeralds and diamonds, as an icon of perfection, a symbol of the best of de Grisogono.

At 163 carats and 41 points, it will be the largest D Flawless diamond ever to appear for sale at auction, a ftting tribute to de Grisogono on the eve of its 25th anniversary. It will also be a shining star at Christie’s ‘Magnifcent Jewels’ auction in Geneva on November 14, 2017.

Christie’s is exceedingly honoured to present this unique, incomparable natural wonder of a diamond to the world."
