$180,000.00
A Pre-Owned Cartier Géométrie & Contrastes pavé necklace in 18K white gold, featuring chalcedony, turquoise, skarn, black lacquer, and 18.76 carats of diamonds.
A powerful embodiment of Cartier’s modernist legacy, this Pre-Owned Géométrie & Contrastes necklace reflects the Maison’s early 20th-century shift toward graphic purity and refined abstraction. Inspired by Louis Cartier’s revolutionary vision, the design embraces geometric structure, sleek lines, and bold material contrasts—capturing the enduring philosophy that less is more.
Expertly crafted in luminous 18K white gold, the necklace features smooth chalcedony accented by skarn and turquoise, creating a sophisticated interplay of color and texture. Dramatic black lacquer adds definition and depth, while 642 brilliant-cut diamonds totaling an impressive 18.76 carats are meticulously pavé-set to deliver exceptional brilliance. Architectural yet elegant, this necklace stands as a commanding statement of Cartier’s Art Deco–inspired high jewelry artistry.
