A rare Kashmir sapphire necklace could set a new auction world record when it goes under the hammer at Christie’s Hong Kong sale on November 27.
The Peacock Necklace — which will lead the Magnificent Jewels auction — contains 21 cushion-cut Kashmir sapphires weighing a total of 109.08 carats. The piece, with its 10.56-carat center sapphire, is estimated at $12 million to $15 million.
Christie’s will also offer an oval-shaped, 10.04-carat, Burmese pigeon’s blood ruby and diamond ring, carrying a presale estimate of $6.9 million to $8.7 million.
“In recent years, [the] price per carat for rubies has increased more than any other gemstone, apart from colored diamonds,” the auction house said last week. “This has been particularly true for pigeon’s blood rubies of significant sizes, which have been generating fervent bidding in auction rooms around the world.”
Other notable lots include a round brilliant-cut, 2.10-carat, fancy-vivid-blue diamond ring, surrounded by circular-cut pink diamonds. The piece, which has been graded as internally flawless, is valued at $3.9 million to $6.4 million. The Ultimate Mogok Blue Treasure, a 396.89-carat Burmese sapphire holding the Guinness World Record for the largest cabochon-cut sapphire, is estimated at $500,000 to $1 million.
The Magnificent Jewels auction will also feature the Moon of Baroda necklace, which Marilyn Monroe wore for the premiere of her 1953 movie Gentlemen Prefer Blondes.
