November in Geneva: Christie's Bets the Month on a Single Collector
On 10 November, Christie's devotes a live sale and a simultaneous online auction to one collection: nearly 300 jewels, Art Deco cases and gold boxes assembled over four decades, expected to realize more than $25 million. A preview, plus a correction to the calendar.
Geneva's November auction season has its first confirmed shape, and it belongs to Christie's. On 10 November, the house devotes a live auction at the Hôtel des Bergues to “Exceptional Jewels & Objects of Elegance: A Connoisseur's Collection”: 123 lots from a single private collection, with a further 152 offered in a dedicated online sale running 5 to 17 November. Nearly 300 lots in all, assembled over four decades by an unnamed private family of collectors, and expected, by Christie's estimate, to realize in excess of $25 million.
The collector's identity has not been disclosed; the taste is the biography.
The pink diamond at the top
The sale is led by a 14.63 carat fancy orangy-pink diamond ring by David Morris, estimated at $1.6 to $2.6 million. The coloured stones behind it are formidable: a pair of Graff cushion-shaped emerald and diamond earrings, each emerald exceeding 17 carats, at $900,000 to $1.5 million; a Bulgari Trombino ring mounted with a 14.38 carat Burmese ruby at $700,000 to $1.2 million; and a pair of Van Cleef & Arpels oval sapphire and diamond earrings at $600,000 to $800,000.
Eight mystery-set masterpieces
The Van Cleef & Arpels section alone would justify the trip. The section's spine is eight mystery-set pieces, made with the technique the maison patented in 1933 to hide every prong so that colour runs unbroken across the surface. The lead is a ruby and diamond Oiseau Mystérieux clip-brooch at $600,000 to $1 million, bought directly from Van Cleef & Arpels in the early 2000s; Christie's calls it one of the finest and most sophisticated versions of a motif the house has used since the 1920s. A mystery-set Fuchsia brooch follows at $400,000 to $600,000, a pair of ruby Cadix earrings at $300,000 to $500,000, and a ruby mystery-set ring at $50,000 to $70,000, with sapphire-set examples completing the group.
Beyond the jewels
What distinguishes this sale from most jewellery auctions is what sits beside the jewels. A strong group of Cartier Art Deco cases shows the maison's command of the decorative arts from the 1920s onward, with debts running from Chinese lacquer to Japanese decorative art: a rock crystal, nephrite, onyx, coral, mother-of-pearl and diamond table cigarette box at $150,000 to $250,000, and a laque burgauté, coral, diamond and silver cigarette case at $100,000 to $150,000. The gold boxes run deeper in time: a German gold and mother-of-pearl snuff-box, Berlin or Dresden, circa 1750, at $40,000 to $60,000; a Marchak and Makowsky enamel, mother-of-pearl and diamond vanity case at $30,000 to $50,000; a Théodule Bourdier malachite, onyx, coral and enamel vanity case at the same estimate.
“This exceptional heritage Collection, assembled and cherished over generations, reflects a legacy of remarkable discernment, refined taste, and an enduring appreciation for beauty that transcends time,” says Rahul Kadakia, President of Christie's Asia Pacific and Chairman of Christie's Luxury. The collector's identity has not been disclosed; the taste is the biography.
Single-owner sales have become the anchor events of the jewellery calendar, and the Connoisseur's Collection shows why: four decades of buying leaves a record that no single season of consignments can imitate. The mystery-set group was assembled piece by piece, bought from the maison itself; the Cartier cases were chosen for their mechanisms and interiors, not only their signatures; the gold boxes reach back to the 18th century because the collector's eye kept travelling further back in time. An auction is usually a market taking its temperature. This one is a portrait with a gavel. The live sale opens at noon Geneva time on 10 November.
A note on the calendar
Readers planning their November should note one correction. Some auction previews recirculating online describe Sotheby's “Vienna 1900: An Imperial and Royal Collection” as an upcoming November sale. It is not. The 207-lot single-owner sale of Viennese imperial and royal jewels took place in Geneva on 6 and 7 November 2023: a white-glove result, every lot sold, more than 82 percent above their high estimates, totalling over CHF 9.6 million against a CHF 3 to 5 million estimate. It was the largest collection of imperial and royal jewellery ever put up for auction, and it is already history.
What is genuinely upcoming, alongside the Connoisseur's Collection, is Christie's separate “Jewels Online: The Geneva Edit”: more than 250 lots closing in mid-November, led by a 7.19 carat pink sapphire ring with an upper estimate of CHF 250,000. Two Christie's sales, one month, one city: November in Geneva is taking shape, and so far it is Christie's month.
