New York—Sotheby’s recent High Jewelry sale in New York raked in $31.4 million as bidders vied for big and fancy colored diamonds, colored gemstones, and signed jewelry from private collections.
With 95 percent of lots sold, the sale marked the highest sell-through rate for a various-owner jewelry auction at Sotheby’s New York, said the auction house.

Top Lot: Graff Diamond

The top lot was a 35.01-carat emerald-cut diamond ring by Graff, which sold for $3.2 million after a three-minute bidding battle, said Sotheby’s, above its estimate of $2 million to $3 million.

“It’s also encouraging to see that the very best white diamonds remain highly desirable, as highlighted by the stunning 35-carat Graff D-color diamond, which captivated all who laid their eyes upon it,”

said Quig Bruning, head of Sotheby’s Jewels, Americas and EMEA.
The ring was part of the “Joie de Vivre: Journey in Jewels” private collection up for sale, which achieved a total of $4.9 million, within its $3.3 million to $5.2 million estimate.
The jewels were gifts from a husband to his wife throughout their 60-plus-year marriage, said the auction house.

Colored Gemstone Highlights

Though a big diamond stole the show, the colored gemstones garnered top dollar as well.

A Colombian emerald and diamond ring by JAR, set with an 8.62-carat emerald, sold for $1.6 million, more than twice the high end of its $500,000 to $700,000 estimate.
A “superb” Kashmir rectangular step-cut sapphire from the 1930s weighing 7.50 carats sold for $1.4 million, above its pre-sale estimate of $500,000 to $700,000.

“Today’s result is a great continuation for what has already been a phenomenal year for jewelry at Sotheby’s,”

said Bruning.

“Much like our High Jewelry sale in Geneva last month, today’s top prices were dominated by exceptional stones of extraordinary color – from the superb emerald and diamond ring by JAR to the mesmerizing 1930s Kashmir sapphire and diamond ring.”

Several colored diamonds also commanded high prices, including a 2.02-carat fancy vivid blue diamond that sold to an online bidder for $1.8 million, beyond the high end of its $1.4 million to $1.5 million estimate.
A ring set with a 5.02-carat oval-shaped fancy pink diamond sold within its estimate, achieving $1.5 million.

Signed Jewelry Success
