Vanderbilt Collection Leads Strong Sale

Geneva—A collection of Belle Époque jewelry that belonged to a Vanderbilt sold for more than four times its low-end estimate at a recent Phillips’ Geneva Jewels auction.

Notable Withdrawals

Notably missing from “The Geneva Jewels Auction: V” sale, held Nov. 10, was a 6.95-carat fancy vivid purplish pink diamond. It was expected to sell for around $9 million but was withdrawn prior to the sale. A Phillips spokesperson stated:

“In agreement with the consignor, Phillips made the decision to withdraw the lot prior to the sale.”

“The Glowing Rose,” a 10.08-carat cushion-shaped brilliant-cut fancy vivid pink diamond estimated at nearly $20 million, was also recently withdrawn from a Sotheby’s sale.

Top Lot: The Vanderbilt Sapphire

The Vanderbilt collection, however, was 100 percent sold, garnering more than $4.2 million. Leading the sale was “The Vanderbilt Sapphire,” a 42.68-carat sugarloaf Kashmir sapphire and diamond brooch mounted by Tiffany & Co. Phillips noted its intricate openwork design accented by old-cut diamonds is quintessentially Belle Époque. The brooch sold for $3.6 million, well above its estimate of $1 million to $1.5 million.

Other Vanderbilt Highlights

Another highlight was a Cartier diamond brooch, originally part of a Belle Époque diamond tiara given to Gladys Moore Vanderbilt, Countess Széchényi, for her 1908 marriage. The brooch sold for $560,582 (estimate: $100,000-$150,000). An emerald and diamond bow brooch and a gold and diamond hair comb also sold above their estimates.

Auction Executive’s Comment

Benoît Repellin, worldwide head of jewelry at Phillips, said:

The Vanderbilt Sapphire brooch
“The results of today’s sale attest to the enduring appeal of period jewels and the discerning eye of our international clients. To bring the jewels of the Vanderbilt family to the world’s stage was a moment of profound privilege. These treasures stand as the purest embodiment of Gilded Age elegance, and the response we have witnessed is a testament to the timeless power of exceptional jewels.”
Overall Auction Results

The overall jewelry auction garnered more than $17 million, with 85 percent of lots sold (90 percent by value). Over 1,600 people visited during the preview and sale, with bidders from 44 countries participating.

Other Notable Lots

The No. 2 lot was an 18.09-carat Kashmir sapphire and diamond ring, selling for $2.8 million. The No. 3 lot, a 10.08-carat light pink-brown old cushion-shaped diamond from Golconda, sold for $880,915 (estimate: $450,000-$600,000).
