Harry Winston Jeweler Buys ‘Pink Legacy’ Diamond For $50 million The “Pink Legacy”, a diamond weighing just under 19 carats, fetched a record 50.375 million Swiss francs ($50 million), purchased by U.S.-based luxury jeweler Harry Winston, Christie’s said on Tuesday. Harry Winston, owned by Swatch whose CEO is Nayla Hayek, daughter of the late Swatch founder Nicolas Hayek, promptly renamed it “The Winston Pink Legacy”, adding it to its collection of rare jewels, the auction house said.

The semi-annual Geneva jewelry sale netted $110 million, with 86 percent of lots finding new owners, including 11 that brought more than $1 million, Francois Curiel, chairman of Christie’s luxury group told reporters.

“The Pink Legacy brought this extremely high price of $50 million, so $2.6 million per carat which is a world record price for a pink diamond,” Curiel, who is also a jewel expert, said. “This stone for me is the Leonardo Da Vinci of diamonds, I don’t think there is anything better.”

Graded “vivid”, the highest rating for a pink diamond’s color, the gem is internally pure with a rectangular cut, and mounted on a platinum ring.

Once owned by the Oppenheimer Family, who built De Beers into the world’s biggest diamond trader, the diamond had a pre-sale estimate of $30 to $50 million. The identity of the seller was not disclosed.

Vivid colored diamonds are the most strongly saturated gems, displaying the optimum hue of the stone. Most pink diamonds of this color weigh less than one carat, the auction house said.
