(Reuters photo)ZURICH - Sotheby's sold a 59.6-carat pink diamond for about $71 million (2.4 billion baht) in Hong Kong, setting the world record for the top auction price for any gem. Hong Kong-based jewellery retailer Chow Tai Fook had the HK$553-million winning bid for the Pink Star after a five-minute contest that included three phone bidders, Sotheby's said Tuesday. In a quirk of auction history, the record price for the Pink Star is some $12 million lower than the $83-million offer Sotheby's adjudicated it for in 2013. The Pink Star was estimated to be worth more than $60 million.
