Christie’s Geneva: Pink Diamond Tops $10 Million
Kashmir Sapphire Sets Record Price
A magnificent ring featuring a 5.18-carat rectangular-cut fancy vivid pink diamond was the top lot at Christie’s Geneva sale of Magnificent Jewels on May 13, selling for $10,709,442 to an anonymous buyer. The diamond is set within an oval-shaped diamond surround and mounted in white gold.

The second top lot was an exceptional unmounted diamond in the pear shape weighing approximately 55.52 carats with D color, internally flawless clarity and excellent polish and symmetry. The stone is also a Type IIa diamond, a rare subgroup of diamonds that includes less than 2 percent of the world’s diamond production. Stones in this group are chemically the purest of all diamond crystals and often have extraordinary optical transparency. The diamond sold for $9,033,721 to an Asian buyer.

An exceptional 35.09-carat Kashmir blue sapphire ring was the third top lot, selling for $7,357,999 to an Asian buyer, shattering its pre-auction high estimate of approximately $4 million and establishing a new world record price at auction for a Kashmir sapphire at more than $200,000 per carat.

According to reports from the world’s top gem labs, this sapphire of significant size exhibits the intensely saturated velvety blue color—often described as the prized “cornflower blue” hue—indicative of the rare sapphires from Kashmir, which set the standard for blue sapphires. In addition, there are no indications that the sapphire has been heated. It also possesses among its superb qualities “a high degree of transparency and finely proportioned cut.” The sapphire is cushion-shaped and set within a white gold ring with triangular-cut diamond shoulders and baguette-cut diamond hoop.

Pearls also fared well, with a late 19th-century single-strand natural pearl and diamond necklace selling for $3,886,861 to the international trade, well above its pre-auction high estimate of approximately $2.5 million. The necklace is composed of 43 graduated natural pearls, measuring approximately 11.1 mm to 7.8 mm, which connect with a circular-cut diamond pinched collet clasp mounted in white gold.

A three-strand natural pearl, cultured pearl and diamond necklace, meanwhile, sold for $2,313,735 to the international trade, more than doubling its pre-auction high estimate. The necklace is composed of 64, 60 and 55 natural pearls and two cultured pearls, measuring approximately 12.2 mm to 5.3 mm, which connect with a single-cut diamond-set clasp mounted in white gold.

Rounding out the top 10 lots was a diamond ring by Bulgari, which sold for $2,057,247 to Laurence Graff, above its pre-auction high estimate of approximately $1.5 million. The diamond, weighing approximately 18.26 carats, is fashioned in a cut-cornered rectangular cut and flanked on either side by tapered baguette-cut diamond shoulders, mounted in platinum and white gold.

Christie’s Geneva sale of Magnificent Jewels achieved a total of $97,515,535, selling 77 percent by lot and 81 percent by value. Overall, 264 of the 341 lots offered were sold.
