An ultra-rare fancy vivid pink diamond has sold for a record US $17.7 million (A$20.09m) to an unnamed buyer in Hong Kong.
Sotheby’s said the internally flawless 8.41-carat stone had been expected to go under the hammer for up to US$15.5 million.
Quek Chin Yeow, deputy chairman of Sotheby’s Asia, said the pear-shaped stone had “attracted keen competition before fetching a wonderful price of HK$137.88 million (US$17.77 million) and setting a world auction record for a fancy vivid pink diamond”.
