$159,000.00
A Pre-Owned Cartier Géométrie & Contrastes transformable pavé necklace in 18K white and yellow gold, featuring onyx and 9.63 carats of diamonds.
A striking tribute to Cartier’s modernist heritage, this Pre-Owned Géométrie & Contrastes necklace reflects the Maison’s early 20th-century evolution toward geometric clarity and refined abstraction. Inspired by Louis Cartier’s revolutionary introduction of sleek lines, contrasting materials, and stylized forms, the design embodies the enduring philosophy that less is more.
Expertly crafted in a harmonious combination of 18K white gold and 18K yellow gold, the necklace features deep onyx elements that emphasize its architectural structure. The composition is elegantly pavé-set with 280 brilliant-cut diamonds totaling 9.63 carats, adding luminous brilliance while preserving the clean, graphic strength of the design. Designed with a transformable structure, this necklace offers versatility in wear while maintaining its bold visual impact—an exceptional expression of Cartier’s avant-garde high jewelry craftsmanship.
