Record Prices at Gem Auctions


Auction records kept breaking in late 2014 as the world’s ultra-wealthy buyers vied for rare, important gemstones. At Sotheby’s October 7 Hong Kong auction, an 8.41 ct GIA-graded Fancy Vivid purple-pink, Internally Flawless diamond (figure 1) drew a winning bid of $17,768,041 from a private buyer from Asia. It was the highest price ever paid for a Vivid pink diamond at auction. And at $2.1 million per carat, it came close to besting the all-time per-carat price achieved by a gemstone.
