This Rare Diamond Ring Could Sell for $2.6 Million at Christie’s Geneva Auction

Geneva is preparing for one of the season’s most compelling luxury auctions as Christie’s presents Exceptional Jewels & Objects of Elegance: A Connoisseur’s Collection, an extraordinary private collection of nearly 300 twentieth-century jewels, Art Deco vanity cases, and finely crafted gold boxes dating from the 18th and 19th centuries.

Assembled over more than four decades, the collection reflects the highly selective eye of a dedicated connoisseur. Its owner sought exceptional gemstones and important creations from some of the world’s most respected jewelry maisons, including Van Cleef & Arpels, Graff, Bulgari, and David Morris.

Expected to realize more than $25 million, the collection stands out not simply for its financial value but for the quality, rarity, and craftsmanship represented across its jewels and decorative objects. Each piece reflects a deeper appreciation for design, technical achievement, and the enduring appeal of fine craftsmanship.

Rahul Kadakia, President of Christie’s Asia Pacific and Chairman of Christie’s Luxury, described the collection as a reflection of remarkable discernment and refined taste. He highlighted its celebrated jewelry creations alongside rare Art Deco vanity cases and exquisitely crafted gold boxes, calling attention to the artistry and innovation represented throughout the ensemble.

Among the most important highlights is a remarkable selection of eight mystery-set creations by Van Cleef & Arpels. The technique, patented by the Maison in 1933, allows gemstones to be mounted without visible prongs, creating uninterrupted surfaces of color while demanding an exceptional degree of precision and craftsmanship. Leading this group is the ruby and diamond Oiseau Mystérieux brooch, estimated at $600,000 to $1 million. The bird of paradise has been an important motif for Van Cleef & Arpels since the 1920s, and the example offered by Christie’s is described as one of the finest and most sophisticated interpretations of the theme. It was acquired directly from Van Cleef & Arpels in the early 2000s.

The Van Cleef & Arpels selection also includes a mystery-set Fuchsia brooch estimated at $400,000 to $600,000, a pair of ruby Cadix earrings estimated at $300,000 to $500,000, and a ruby mystery-set ring estimated at $50,000 to $70,000. Sapphire-set creations further demonstrate the Maison’s celebrated approach to color and technical innovation.

Exceptional gemstones form another major strength of the collection. At the forefront is a 14.63-carat fancy orangy-pink diamond ring by David Morris, carrying an estimate of $1.6 million to $2.6 million. Its extraordinary color and size make it one of the auction’s standout jewels.

Graff is represented by a breathtaking pair of cushion-shaped emerald and diamond earrings, each featuring an emerald exceeding 17 carats. The pair is estimated at $900,000 to $1.5 million. Another important highlight is an iconic Bulgari Trombino ring set with a fine 14.38-carat Burmese ruby, estimated at $700,000 to $1.2 million. Van Cleef & Arpels also contributes a spectacular pair of oval sapphire and diamond earrings, weighing [20.66 or 20.60 — confirm] and 18.99 carats, with an estimate of $600,000 to $800,000.

Beyond jewelry, the collection reveals an equally strong appreciation for objects of elegance and decorative craftsmanship. A distinguished group of Cartier vanity cases demonstrates the Maison’s extraordinary mastery of the decorative arts, particularly during the Art Deco period. Created from the 1920s onwards, these cases draw inspiration from artistic traditions including Chinese lacquer work and Japanese decorative arts. Their appeal extends beyond their visual beauty, with ingenious mechanisms, balanced hinges, and carefully conceived interiors revealing the technical sophistication associated with Cartier.

The collection also includes exceptional gold boxes, snuff boxes, and pill boxes dating from the 18th and 19th centuries. Finely carved hardstones, sculpted cameos, and elaborate enamelwork reveal the extraordinary skill of jewelers, goldsmiths, and silversmiths from earlier eras. Oriental scenes, floral designs, and mythological subjects further enhance these objects, transforming functional pieces into miniature works of art.

Exceptional Jewels & Objects of Elegance: A Connoisseur’s Collection will be presented through two dedicated sales in Geneva. The live auction will take place at the Hôtel des Bergues on November 10 and feature 123 exceptional pieces. At the same time, an online sale will run from November 5 to 17, offering 152 more jewels from the collection.

For collectors and jewelry enthusiasts, the sale’s significance lies in its remarkable combination of rarity, provenance, craftsmanship, and design. From Van Cleef & Arpels mystery-set jewels and exceptional colored gemstones to Cartier Art Deco cases and historic gold boxes, the collection offers an unusually broad portrait of luxury across generations.
