Christie’s Magnificent Jewels Hong Kong auction on Nov 28 saw the sale of the 14.93 carat Pink Promise diamond for an incredible $31,861,000 – approximately $2.13 million per carat. Described by Christie’s as the “Picasso of the Pink Diamond world,” this is a huge, dazzling pink oval stone with mixed cuts, flaunting a Fancy Vivid Pink color—a designation given by the Gemological Institute of America (GIA), representing the most prized color grading in pink diamond history. The oval stone was set in a platinum ring and surrounded by diamonds, and the estimates for its auction ranged from $28 million to $42 million.
