Under the hammer: The Art of de Grisogono diamond necklace will tour New York and Dubai before being auctioned at Christie’s in Geneva this November
Geneva-based high-jeweller de Grisogono has partnered with Christie’s auction house on The Art of de Grisogono, a collaboration that places exceptionally rare and exquisite diamonds under the hammer.
Setting the bar, and carat, high is an extraordinary necklace featuring a D-colour, flawless IIA type diamond. In layman’s terms, this means it is a completely colourless, colossal diamond and the largest of its kind to ever come to auction, weighing 163.41 carat.
The well-travelled, supremely rare rock has toured London and Hong Kong and is currently doing the rounds in New York and Dubai before going on sale in Geneva on 14 November 2017, as part of the Magnificent Jewels sale at the Four Seasons Hotel des Bergues.
The sublime stone is cut from a 404.2 carat rough diamond found at the Lunda Norte province in Angola in 2016. It is the 27th largest diamond ever found globally and the largest in Angola.
Once purchased by de Grisogono, it was analysed in Antwerp and cut in New York, where a team of ten diamond specialists finessed the unique emerald-cut stone, which is suspended from an asymmetrical necklace in emerald and diamonds.
"I have never had a problem finding creative ideas, but this time there was the immense pressure of ‘dressing’ such an amazing diamond,” said Fawaz Gruosi, president, owner and founder of de Grisogono. “I couldn’t do something simple or that had already been seen. I needed a design that was outside of the box."
Gruosi founded de Grisogono in 1993, following stints at Harry Winston and Bulgari. The private high jewellery house is famed for its glamour, daring creativity and technical brilliance and, in an often predictable market, it remains a fiercely independent and contemporary trailblazer.
The Art of de Grisogono auction coincides with the fine jeweller's 25th anniversary and as Rahul Kadakia, international head of Christie’s jewels, so rightfully put it, “propels de Grisogono into a class of its own."
