The Clark Pink Diamond Sells for Record $15.7 Million

The 9-ct. Belle Epoque cushion-cut, fancy vivid purplish pink diamond ring from the estate of Huguette M. Clark sold for $15.7 million.

NEW YORK — A 9-carat pink diamond from the estate of Huguette M. Clark sold for more than $15.7 million, after intense, competitive bidding that led to an eruption of applause on the crowded auction floor at Christie’s Tuesday. It is the most valuable pink diamond ever sold in the United States at auction, according to the auction house.

The Belle Epoque cushion-cut, fancy vivid purplish pink diamond, known as “The Clark Pink,” was estimated to fetch $6 to $8 million. Clark, one of the last heiresses of America’s Gilded Age, died in May, 2011, at the age of 104. Her collection of 12 lots drew intense intentional attention because she lived a reclusive life in her later years and her jewels were believed to have been kept in a vault unseen since the 1940s.

The entire collection, which included picture frames, a clock, an American flag lapel and jewelry pieces by Cartier and Tiffany, took in a total of $20.8 million against a presale estimate of $9 million. Other significant items from the estate sale included:

* A 19.86-carat rectangular-cut diamond ring by Cartier that sold for $3.1 million;
* An Art Deco diamond bracelet by Cartier that sold for $578,500; and
* A ruby, sapphire, emerald and gold bracelet by Tiffany & Co. that sold for $266,500.

The collection was part of Christie’s Magnificent Jewels sale Tuesday that had 305 lots that included signature jewels, items from several estates and serious diamonds. It took in a total $70.7 million, with 95 percent of the items sold by lot and 97 percent of the estimated price realized.
