Vanderbilt Family Treasures Sell in Phillips’s $17 M. Jewelry Auction
Auction Highlights

Twelve lots offering storied jewels from the Vanderbilt family sold out in Phillips’s “Geneva Jewels Auction” on Monday, making up a significant portion of the total of CHF 13.7 million (around $17 million) raked in by the sale.

Ninety-six of 113 total lots sold, measuring in for an 85-percent sell-through rate.

“The results attest to the enduring appeal of period jewels and the discerning eye of our international clients,”

said Benoît Repellin, Phillips worldwide head of jewelry.

Vanderbilt Collection Success

The Vanderbilt family jewels brought in CHF 3.42 million ($4.25 million), four times the low estimate for the lots. The top lot was “The Vanderbilt Sapphire,” a Gilded Age treasure featuring a 42-karat sugarloaf Kashmir sapphire and a diamond brooch crafted by Tiffany & Co. It sold for CHF 2.88 million ($3.57 million), above its estimate of $1 to $1.5 million.

“To bring the jewels of the Vanderbilt Family to the world’s stage was a moment of profound privilege,”

Repellin said in a statement.

“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.”

Notable Sales and Buyer Interest

Phillips noted that 90 percent of signed jewels in the auction sold. Repellin highlighted the sale of a Cartier Magnificent diamond brooch for $560,582, a Bulgari “Serpenti” belt for $368,383, and several lots of Cartier “Panthère” jewels.

The auction house said it hosted more than 1,600 visitors during a preview and the sale itself, with bids received from aspiring buyers in 44 countries. A “Geneva Jewels” online auction continues through November 13, and Phillips will lead a “New York Jewels Auction” at its New York headquarters on December 8.
