A 6.04-carat blue diamond has sold at Sotheby's in Hong Kong for $7.98 million, the highest price ever paid for a rare gemstone at auction, according to Reuters.
"The bidding was fast and furious and you know it's not as if one could go out and buy another one," Quek Chin Yeow, head of Jewellery Asia at Sotheby's, tells BBC News. "It's as rare as getting a Renoir or a wonderful Rothko. When you look at the stone, it sings. The cutting is wonderful."
