Diamond brooch expected to sell for $8M


Geneva--A Van Cleef & Arpels brooch featuring a 96.62-carat fancy vivid yellow diamond is expected to fetch up to $8 million at Sotheby’s Nov. 13 sale of Magnificent Jewels in Geneva.

Made in 1971, the “Walska Briolette Diamond” brooch features the 96.62-carat diamond in the beak of a yellow gold Bird of Paradise set with yellow and white diamonds, emeralds and a cabochon sapphire.

The briolette diamond detaches to form a pendant and the bird’s wings become a pair of earrings.

Van Cleef & Arpels purchased the 96.62-carat fancy vivid yellow diamond at a Sotheby’s New York auction. The diamond was part of the collection of Madame Ganna Walska, a Polish-born opera singer and jewelry connoisseur who was born in 1887 and died in 1984.

A year later, Van Cleef & Arpels used the diamond to create the transformational Walska Briolette Diamond brooch after being commissioned by an American collector.

“The Walska Briolette Diamond brooch is the perfect demonstration of how a great jeweler can emphasize the beauty of a spectacular stone by transforming it into a unique piece. The historic diamond, which is of an extraordinary size for an antique-cut briolette, comes back on the market after 42 years, in a fabulous bespoke piece of jewelry,” said David Bennett, chairman of Sotheby’s jewelry division in Europe and the Middle East and chairman of Sotheby’s Switzerland.

Sotheby’s Nov. 13 sale is also the auction that includes the 59.60-carat “Pink Star” diamond, an oval-cut diamond that is the largest internally flawless fancy vivid pink ever graded by the Gemological Institute of America.

Expected to sell for as much as $60 million, the stone could break the current world record for any gemstone sold at auction.
