Harry Winston, owned by Swatch, whose director is Neilah Hayek, the daughter of the late Swatch founder, Nicholas Hake, immediately changed her name to "Winston Pink's Legacy" and added her to her rare jewelry collection, the auction house said.
The sale of semi-finished jewelry reached $ 110 million, with 86 percent of the plots finding new business owners, including 11 that brought in more than $ 1 million, said Francois Curiel, chairman of Christie's luxury group.
"Pink's legacy brought a very high price of $ 50 million, so $ 2.6 million per carat is a world record price for a pink diamond," says Curiel, who is also a jeweler. "This stone for me is Leonardo da Vinci of diamonds, I do not think there's anything better."
The "live" grade, the highest rating of the pink color of the diamond, a pure inner pearl with a rectangular cut installed on the platinum ring.
In the past, the Oppenheimer family, which built De Beers into the world's largest diamond dealer, had a pre-estimate estimate of $ 30 million to $ 50 million. The identity of the seller was not disclosed.
Essential colored diamonds are the most saturated gems, which show the optimal shade of stone. Most of the pink diamonds of this color weigh less than one carat, said the auction house.
At least five people filed a call to the pink stone, but the winner was Harry Winston's representative in the front row, Curiel said.
An important Asian collector was under the direct bidder, Rahul Kadakia, international head of jewelry at Christie's told reporters.
"The stone is about to be called" Pink to Legacy Diamond, "which Ms. Hayek is moving in. In 2013 they made their first important purchase after the acquisition of Winston, which was 101 carats flawless diamonds, which are named Winston Heritage. With this stone they started the heritage collection, "he said.
