Despite the absence of “The Allnatt,” Sotheby’s Geneva jewelry auction totaled $34 million, with 90 percent of lots sold.

This 101-carat yellow diamond, named “The Allnatt,” was withdrawn from Sotheby’s recent “Magnificent Jewels and Noble Jewels” sale.
Geneva—A highlight of Sotheby’s recent Geneva jewelry auction was a 101-carat yellow diamond dubbed “The Allnatt,” but it was withdrawn from the sale.

“The Allnatt” is a 101.29-carat fancy vivid yellow diamond mounted in a Cartier brooch. It had a pre-sale estimate of CHF 5.6 million to 6.5 million ($6.2 million to $7.2 million).

“It has been a privilege to present ‘The Allnatt’ to collectors and connoisseurs over the past few months. Following discussions with the consignor, they have elected to retain this jewel,” Sotheby’s said in a statement to National Jeweler.

The “Magnificent Jewels and Noble Jewels” sale, held Tuesday, totaled CHF 31.1 million ($34.3 million) with 90 percent of lots sold, and 96 percent of lots exceeding their lowest estimates.

“This edition of our ‘Magnificent Jewels and Noble Jewels’ sale was marked by a succession of outstanding results, affirming the continued strength in the market for jewels and gemstones of the finest quality,” said Catharine Becket, head of Magnificent Jewels, Geneva.

North America accounted for the largest percentage of bidders and buyers, said Sotheby’s, followed by Hong Kong and China, then the U.K., Switzerland, India, and Italy.

The sale continues to draw in younger bidders, said the auction house. More than 40 percent of bidders were between the ages of 20 and 49.

The top lot of Sotheby’s Geneva jewelry auction was this 37.61-carat round-cornered square brilliant-cut diamond.

“The jewel, offered with the original design drawing, is regarded as one of Cartier’s most iconic designs and is perhaps the only recreation of the original Duchess of Windsor flamingo brooch ever issued by the legendary maison,” the auction house said.

Its plumage is set with calibré-cut rubies, sapphires, and emeralds, while the beak has a blue sapphire and yellow sapphire. Its eye is a blue sapphire while its neck, body, and hinged legs are set with brilliant-cut pavé diamonds.
