Christie’s Geneva The Magnificent Jewels Sale achieved a total of CHF105,422,500 ( $106,070,751) on 14 November (Tuesday), led by The Art of de GRISOGONO, Creation 1.
The colourless diamond was made from a 404.2 carat rough stone - the largest rough white diamond ever found in Angola. It was brought to the Geneva headquarters of de GRISOGONO and was transformed into asymmetric necklace featuring 18 emerald-cut diamonds on one side, with the 163.41-carat diamond as the centrepiece.
It was the largest flawless D-colour diamond ever auctioned. D is the highest colour grade attributed to a diamond, indicating that the stone is completely colourless, and thus extremely rare.
The bidding started at CEF20m and the necklace was hammered down for CEF 29.5m. It was sold to a telephone bidder, who wished to remain anonymous, for CEF33.5m (US$33.7m) with buyer’s premium, setting a world record for any D-colour flawless diamond.
But some showed disappointment as they had expected the rare piece to fetch a higher price.
Tobias Kormind, head of 77 Diamonds
“I am disappointed that the Art of de Grisogono didn’t sell for a more dazzling price,” said Tobias Kormind, head of 77 Diamonds, a large European online diamond jeweller. "The diamond is over 40% larger than the 118.28 D Flawless oval sold by Sotheby's in 2013 for $30.6m and the price failed to reflect that comparison.
Le Grand Mazarin
Another highlight of the sale was a Le Grand Mazarin, a light pink diamond of 19.07 carats that once belonged to Louis XIV and Napoleon. It was the final lot of the auction and sold for CHF14,375,000 / $14,463,393.
