A rare 9.75 carat fancy vivid blue diamond sold for a world record US$32,645,000 at Sotheby’s in New York last night. That is US$3,348,205 per carat, a world record per carat for any diamond. From the celebrated collection of Mrs. Paul Mellon it has gone to a private collector in Hong Kong, who has named the stone The Zoe Diamond. No less than seven bidders competed in a 20 minute bidding battle.
Gary Schuler, Head of Sotheby’s Jewelry Department in New York, commented: “From the moment I saw this diamond, I knew that it would be one of the most important stones that I will ever have the privilege of presenting at auction. It was incredible to see each of my colleagues experience the diamond for the first time, watching as the blue hue warmed and intensified in front of them with every minute in natural light. Mrs Mellon’s diamond absolutely deserves the place in the record books that it achieved tonight.”
The previous auction record for any blue diamond was US$24,311,191, set by the Wittelsbach Diamond at Christie’s London in December 2008. The previous per-carat auction record for any diamond was US$2,398,152, set by a 14.82 carat Fancy Vivid Orange Diamond at Christie’s in Geneva in November 2013. Sotheby’s New York auctions of the Mellon Collection continues through Sunday.
