Van Cleef & Arpels Zip necklace-bracelet tops Phillips Geneva sale

The most talked-about lot in Phillips’ Geneva Jewels Auction was a Van Cleef & Arpels Zip necklace-bracelet, a coral, chrysoprase and diamond design that climbed to CHF619,600, or $793,346, well past its CHF260,000 to CHF480,000 estimate. Cataloged as lot 399, it arrived with two fitted cases and a pouch stamped Van Cleef & Arpels, small details that matter in this market because presentation, completeness and provenance often travel together.

Phillips described the piece as a 2012 necklace-bracelet combination with a gold zipper set with carved chrysoprase, coral cabochons and diamond motifs, finished with a tassel of coral and chrysoprase beads. The necklace’s approximate 450 mm inner circumference places it squarely in the realm of high jewelry designed to transform on the body rather than sit as a static ornament. That convertibility is part of the Zip’s enduring seduction: it can be worn open as a necklace or closed as a bracelet, a sleight of hand that gives one jewel two distinct lives.

Van Cleef & Arpels traces the Zip to 1950, when the Maison turned the logic of a zipper patent from 1938 into a piece of jewelry after more than 10 years of research and development. That history gives the design the rare combination auction buyers chase: a recognizable silhouette, technical invention, and unmistakable house pedigree. In a market crowded with signed jewels, the Zip stands apart because its concept is not just decorative, but genuinely ingenious. It is a clasp, a line, a ribbon of gold and gems, and a piece of wearable engineering.

The Geneva result also reflected the strength of the room around it. The sale, held May 11, 2026, at Hotel President in Geneva, totaled about $7 million, with 86 percent of lots sold and 85 percent sold by value. Phillips’ push into historic jewels and notable provenances made the context especially apt for a piece like this. For collectors, a result this strong does more than reward one jewel: it reinforces the resale logic behind signed transformable designs and keeps attention fixed on later Zip variations, as well as on more accessible vintage-inspired jewels that borrow the same serpentine movement, hidden mechanism and maison-led glamour.
