“The Orange,” the largest fancy vivid orange diamond ever to appear at auction will be the star lot at Christie’s Magnificent Jewels Auction on November 12.
The 14.82-carat diamond is expected to fetch between $17 million and $20 million at the sale.
Pure orange diamonds, which get their orange color from nitrogen, are exceptionally rare. Also called “fire diamonds,” the largest of the few fancy vivid orange diamonds sold at auction was below 6 carats.
“Christie’s Geneva is proud to offer collectors the best of the best in the world of jewelry,” said Rahul Kadakia, head of Jewellery at Christie’s Switzerland and Americas. The auction will feature more than 280 lots.
The Gemological Institute of America, which graded the diamond and issued its report, recently said: “Strongly colored diamonds in the orange hue range rarely exceed three or four carats in size when polished. (This diamond) is almost four times larger than that size range.”
