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’ recent sale.

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It was expected to sell for around $9 million, but was withdrawn from the sale, as was first reported in Forbes.

A Phillips spokesperson said “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a 10.08-carat cushion-shaped brilliant-cut fancy vivid pink diamond estimated to sell for nearly $20 million, was also withdrawn from a recent Sotheby's sale.

The Vanderbilt collection, however, was 100 percent sold, garnering more than $4.2 million.

The jewels up for auction belonged to Gladys Moore Vanderbilt, Countess Széchényi, who was the daughter of Cornelius Vanderbilt II and the great-granddaughter of Cornelius Vanderbilt, who built the family fortune.

Leading the sale was “The Vanderbilt Sapphire,” a 42.68-carat sugarloaf Kashmir sapphire and diamond brooch mounted by Tiffany & Co.

The Vanderbilt Sapphire brooch
“The Vanderbilt Sapphire” brooch sold for $3.6 million at a recent Phillips sale.


It features an intricate openwork design accented by old-cut diamonds, a style that is quintessentially Belle Époque, said Phillips.

The brooch sold for $3.6 million, well above its estimate of $1 million to $1.5 million.

Another highlight from the Vanderbilt collection was a Cartier diamond brooch that originally was part of a Belle Époque diamond tiara, which had eight lily sprays with interchangeable pear-shaped amethysts and diamonds. The tiara was later taken apart.

This diamond brooch, once part of a Cartier tiara that belonged to Gladys Moore Vanderbilt, Countess Széchényi, sold for $560,582.


The tiara was given to Gladys by her mother to celebrate her marriage to Count László Széchényi in 1908.

The brooch sold for $560,582, well above its pre-sale estimate of $100,000 to $150,000.

An emerald and diamond bow brooch that belonged to Gladys, as well as her gold and diamond hair comb, also sold above their estimates.



“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,” said Benoît Repellin, worldwide head of jewelry at Phillips.

“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.”

The overall jewelry auction garnered more than $17 million, with 85 percent of lots sold and 90 percent sold by value, with signed jewels doing especially well.

More than 1,600 people visited during the preview and sale, said Phillips, with bidders from 44 countries participating in person, over the phone, and online.

The No. 2 lot was an 18.09-carat Kashmir sapphire and diamond ring, which sold for $2.8 million.

This 10.08-carat light pink-brown old cushion-shaped diamond sold for $880,915.


The 10.08-carat light pink-brown old cushion-shaped diamond is said to be from the historic Golconda region in India and, like Swift’s ring, has a combination bezel-prong setting in yellow gold.

It sold for $880,915, above its $450,000 to $600,000 pre-sale estimate.

Another highlight of the auction was a Van Cleef & Arpels 1920s diamond sautoir with all the geometric flare of the Art Deco era, set with a 10.79-carat step-cut diamond.
