A Nearly 15 Carat Fancy Vivid Orange Diamond to Hit the Auction Block at Christie’s Geneva on November 12

A 14.82 carat VS1 type IIa pear-shaped Fancy Vivid Orange diamond, graded by the Gemological Institute of America (GIA), will headline Christie’s Magnificent Jewels sale in Geneva on November 12. “The Orange” is the largest of its kind to feature in an auction and is estimated to fetch between $17 million and $20 million. As rare as colored diamonds are as an entity, pure orange diamonds without any secondary colors, or overtones, are remarkably few and far between in nature. Orange diamonds obtain their color from the influence of nitrogen during crystallization.

The last Fancy Vivid Orange diamond to be sold at auction was the 5.54 carat “Pumpkin Diamond,” which netted $1.3 million at Sotheby’s in 1997. The winning bid was secured by Ronald Winston, son of Harry Winston. “The Orange” is more than twice the size of “The Pumpkin Diamond.”


The GIA has recently observed that orange diamonds of strong color typically do not achieve more than three or four carats once polished. Yet “The Orange” is almost four times that expected size range. According to the colored diamond grading system implemented by the GIA, the laboratory notes that the smaller the amount of yellow existing in a diamond of orange color, the rarer it becomes. As rare as pink and blue diamonds are, even they make appearances in auctions more frequently than orange diamonds, merely underscoring the exceptional rarity of the orange diamond.
