Cartier, Van Cleef and David Webb Headline Bonhams California Jewelry Auction

Bonhams announced on Feb. 19, 2026 that its Fine Jewelry: California sale is scheduled for early March in Los Angeles and that the online lot gallery lists 318 lots. The press material foregrounds estate and signed jewels from Cartier, Van Cleef & Arpels and David Webb while placing the entire sale within an overall estimate range of US$800–US$75,000.

The lot listing reads like a shopping tour through 20th century atelier names and collectible house signatures. Numbered highlights begin with TIFFANY & CO.: AN 18K GOLD AND DIAMOND BRACELET as lot 1 and continue through CHIAMPESAN: A 14K GOLD NECKLACE, BULGARI: AN 18K GOLD AND DIAMOND 'MONETE' RING, and HERMES: AN 18K GOLD 'CHAÎNE D'ANCRE' NECKLACE, CIRCA 1970. Also catalogued are TIFFANY & CO.: A PAIR OF 18K GOLD EARCLIPS, 1995; CARTIER: AN 18K GOLD AND STAINLESS STEEL BRACELET; and BULGARI: AN 18K GOLD 'PARENTESI' WRISTWATCH. The auction highlights further name David Webb twice - an 18K gold 'Scallop' bracelet and an 18K gold, platinum, rock crystal and diamond brooch pendant - alongside early 20th century pieces such as an EMERALD AND DIAMOND RING, CIRCA 1915 and a LOUIS COMFORT TIFFANY FOR TIFFANY & CO.: AN 18K GOLD AND TOURMALINE PENDANT BROOCH, CIRCA 1911.

Bonhams’ sale page makes bidder obligations starkly clear; the site displays the following notice: "ALL BIDDERS MUST AGREE THAT THEY HAVE READ AND UNDERSTOOD BONHAMS' CONDITIONS OF SALE AND AGREE TO BE BOUND BY THEM, AND AGREE TO PAY THE BUYER'S PREMIUM AND ANY OTHER CHARGES MENTIONED IN THE NOTICE TO BIDDERS. THIS AFFECTS THE BIDDERS LEGAL RIGHTS." The page also advises prospective buyers that, "If you have any questions about the Conditions of Sale, please contact your nearest client services team."

Recent Bonhams results set a context both encouraging and exacting for the California catalogue. Rapaport documented a December 8 New York Jewels auction where "A ring with a 6.92-carat sapphire brought in just over $1 million ... more than twice its $500,000 high estimate," and that sale totaled over $5 million with successful lots from Tiffany & Co., David Webb and Cartier. Earlier Bonhams California sales offer provenance-rich narratives: JCK previewed a Sept. 26, 2025 sale that led with a Raymond Yard diamond necklace centering a 5.1 ct. oval opal - set in platinum with approximately 6.3 cts. diamonds and believed originally designed as a ring - and noted the piece belonged to Doris Merrill Magowan; JCK recorded a presale estimate of $30,000–$50,000 and observed that "Bonhams anticipates strong international interest and similarly impressive results for the upcoming auction."

With 318 lots, named maison pieces and an explicit buyer obligations notice, Bonhams’ early March California sale in Los Angeles positions signed and provenance-rich jewels at the center of its offering; the market will judge whether the consignments achieve the headline-making results Bonhams and recent New York sales have demonstrated.
