Sotheby’s to Sell 81ct. Flawless Diamond

80.88 carat emerald cut diamond

A flawless white diamond with a high estimate of $19 million will feature in Sotheby’s Magnificent Jewels and Jadeite auction in Hong Kong next months.

The emerald cut, 80.88 carat, D color, type IIa stone is valued at $12.8 million to $19.1 million USD, and is one of only five emerald cut diamonds over 80 carats offered in auction history, Sotheby’s said Monday.

A 10.64 carat, fancy vivid purplish pink, internally flawless diamond, polished as a radiant cut, with the outline of an emerald cut, is set to go under the hammer at the October 7 sale for $19.1 million to $25.5 million. The auction house will also feature a necklace by designer Anna Hu, containing a 100.02-carat, fancy intense yellow diamond, estimated at $5.1 million to $6.4 million.

“It is thrilling to be able to bring together three top class diamonds this autumn, all of which are exceptional in quality and rarely seen on the market, let alone presented in a single sale,” said Yvonne Chu, acting head of Sotheby’s Hong Kong jewelry division. “We are set for a bright season ahead.”

Also up for auction are an 11.88 carat, pigeon’s blood Burmese ruby and diamond ring, mounted by designer Raymond Yard and valued at $5.6 million to $8.2 million, and a jadeite bead necklace with a diamond clasp, estimated at $3.2 million to $4.1 million.

Other notable items include a 19th century 37.29 carat sapphire and diamond brooch. The piece, which Richard Burton gave to Elizabeth Taylor during their marriage, has a presale estimate of $1.7 million to $2.3 million.

Sotheby’s will showcase the pieces throughout Asia before the auction.
