Sotheby’s closes spring jewelry season with Cartier Art Deco treasures
A seven-piece Cartier Art Deco group from Phyllis Frank leads Sotheby’s London sale, where a 5.72-carat Kashmir sapphire and a Bulgari Trombino ring sharpen the draw.
Cartier’s Art Deco language is the selling point at Sotheby’s London, where a seven-piece private collection from former model Phyllis Frank has become the visual anchor of a 225-lot spring fine jewelry sale. The online auction runs through 3 June and spans more than two centuries of design, from 19th-century and Belle Époque jewels to Art Deco, mid-20th-century pieces, and contemporary work.
The Frank group is compact but telling: a diamond bangle, a lapis bracelet, and a sapphire and diamond double-clip brooch sit among the seven pieces, each one built around the crisp geometry that made Cartier synonymous with the Art Deco period. Diamonds, sapphires, and lapis lazuli give the collection its cool, architectural palette, the kind that still reads as modern because the proportions are disciplined and the surfaces are so cleanly resolved. Phyllis Frank, identified in auction material as Phyllis Frank née Francatelli, was also an original model for Lucile Ltd., the fashion house of Lady Duff Gordon, which adds a strand of couture history to the jewelry’s provenance.
That combination of design purity and named ownership is exactly what keeps collectible jewelry buoyant. Cartier Art Deco pieces do not simply survive the market; they define a category of demand, especially when the forms are strong enough to stand on their own and the signatures are easy to read. Sotheby’s says the Frank jewels exemplify Cartier’s geometry and design in the Art Deco movement, and the statement is borne out by the pieces themselves: restrained, graphic, and unmistakably made for a client who understood fashion as a complete expression.
Beyond the Cartier suite, the sale’s top lots show the same appetite for rarity and finish. A 5.72-carat Kashmir sapphire ring, set within a star-shaped diamond surround, brings the mineral romance collectors expect from the Kashmir name. An 8.03-carat brilliant-cut diamond ring, graded G color and VS2 clarity, offers a different proposition, one built on size, brightness, and clean grading. A Bulgari Trombino sapphire ring with a 6.6-carat sapphire adds another layer of design pedigree, while antique pearl jewels underscore how signed vintage and period pieces continue to command attention.
Bidding opened before the June 3 closing date, and the lots are set to close at one-minute intervals. That brisk pacing suits a sale in which the most memorable objects are not just valuable, but legible: jewels with clear design codes, real provenance, and the kind of enduring style that still feels like a benchmark.
