Briolette diamond sets $13.9 million auction record in Hong Kong
HONG KONG (REUTERS) - The biggest briolette-style diamond ever to appear at auction set an US$11 million (S$13.9 million) record when it sold to an anonymous Asian buyer in Hong Kong on Tuesday, auctioneer Christie's said.
The 75.36-carat briolette - a gem cut into a three-dimensional waterdrop shape - is suspended on a chain of diamonds. Although it fell short of a top pre-sale estimate of US$12.5 million, it beat the US$10.8 million record set by a 10.48-carat fancy deep blue briolette sold by Sotheby's last year.
The Type IIa diamond - similar to the Koh-i-Noor diamond set into British Queen Elizabeth's crown - is exceptionally rare, according to Christie's jewellery specialist Chiang Shiu-Fung.
"Briolette is so special because we have to find a piece of rough that is big enough to cut (into) a briolette style,"Chiang said.
