A necklace featuring a 163.41-carat diamond was sold for $33.7 million at Christie’s Geneva sale on Tuesday. That set a record price for a D-color, flawless stone sold at auction, Christie’s said.
The rectangular-cut diamond, set in an emerald-and-diamond necklace, went for $206,266 per carat, Christie’s reported. The diamond was sold to an anonymous telephone bidder.
“Swiss-based jeweler de Grisogono designed and manufactured the necklace, having bought the 404.20-carat rough from the Lulo mine in Angola for $16 million. The project was carried out in partnership with Dubai-based diamond manufacturer Nemesis International.
De Grisogono unveiled the jewel, named The Art of de Grisogono, Creation 1, in September. A rare feature of the piece is that the user can wear the center stone either in its necklace form or as a bracelet.” says Rapaport.
Fawaz Gruosi, de Grisogono’s founder and creative director, told Rapaport News he expected the jewel to fetch $30 million to $40 milllion.
Total proceeds from the Magnificent Jewels auction made up $106.1 million, with Christie’s selling 88% of total lots by value, it said. A separate auction of Art Nouveau and Art Deco pieces on Monday yielded a combined $12.4 million.
