Sotheby's Sells Deep Blue Briolette Diamond for $1M Per Carat

Sotheby's Geneva sale of Magnificent Jewels on Wednesday garnered $81,092,327 (CHF 76.7 ‎million) selling 88.5 percent by lot and 94 percent by value.‎

The top lot was a rare, 10.48-carat, flawless, fancy deep blue briolette diamond, which sold to ‎Laurence Graff for $10,860,146 (CHF 10.3 million), or $1.04 million per carat, well above its high-end ‎presale estimate of CHF 4.2 million. Sotheby’s noted the price set a new record at auction for a ‎deep blue diamond and for a briolette diamond. This remarkable stone (pictured) was ‎‎''unsullied by secondary colors'' and in terms of polish and symmetry, was awarded the highest ‎possible grade by the Gemological Institute of America (GIA), according to Sotheby's.‎

‎“This was truly one of the finest offerings of colored stones in 20 years. The quality of ‎sapphires, rubies and emeralds was simply outstanding and this was reflected in the prices ‎realized,” said David Bennett, the chairman of Sotheby’s jewelry department in Europe and the ‎Middle East. “Exceptional diamonds and jewels, such as the record breaking fancy deep blue ‎diamond and the pair of noble ruby earrings, attracted intense bidding from several ‎continents.”‎

The second top lot was a pair of cushion-shaped, 11.46-carat and 11.64-carat, Burmese rubies ‎pendent ear clips, which sold to a private Asian buyer for $3.52 million (CHF 3.33 million), or ‎‎$152,396 per carat. The ear clips  were assembled in 1921 and given as a gift to HSH Princess ‎Max Egon zu Hohenlohe-Langenburg, by her parents Trinidad von Scholtz Hermennsdorff, ‎Duchess of Parcent, and Ambassador Manuel de Yturbe of Mexico, on the occasion of her ‎wedding.‎

A conch pearl, enamel and diamond bracelet by Cartier sold to a European private buyer for ‎‎$3.46 million and a 39-carat, step-cut Burmese sapphire and diamond ring sold for $2.9 million, ‎or $75,088 per carat. ‎
