At this year's Phillips’ Geneva Jewels Auction: V on November 10, 2025, the spotlight center-focused on The Vanderbilt Sapphire, a stunning Belle Époque masterpiece epitomizing the grandeur and fine gem-setting artistry of the Gilded Age. Part of the Vanderbilt Family Jewels collection, the piece led a 100% sold group that realized CHF 3.42 million / US$ 4.25 million, achieving four times its low estimate.
Period jewels and signed creations demonstrated exceptional strength as a whole, with 90% of lots sold, many exceeding their high estimates. The sale featured iconic designs by historically renowned design houses like Tiffany & Co., Cartier, and Bulgari, including the celebrated Cartier “Panthère” jewels and Bulgari “Serpenti” belt, each representing distinct hallmarks of craftsmanship and design evolution in 20th century jewelry history.
Phillips’ Worldwide Head of Jewellery, Benoît Repellin, described the results as a testament to the “timeless power of exceptional jewels,” underscoring collectors’ continuing appreciation for artistry, provenance, and the refined aesthetics of historic gem-set works.
The auction drew over 1,600 visitors and bidders from 44 countries, reflecting sustained international enthusiasm for period jewels. Phillips’ Geneva Jewels Online Auction continues until 13 November, followed by the next live sale in New York on 8 December.
