Pre-Owned Cartier Géométrie & Contrastes Necklace in 18K White Gold with Onyx, Cultured Pearls, and Diamonds
A Pre-Owned Cartier Géométrie & Contrastes necklace in 18K white gold, featuring onyx, cultured pearls, brown diamonds, and mixed diamond cuts totaling 16.70 carats.
A striking embodiment of Cartier’s modernist evolution, this Pre-Owned Géométrie & Contrastes necklace reflects the Maison’s early 20th-century departure from ornate tradition toward graphic clarity and refined abstraction. Inspired by Louis Cartier’s revolutionary introduction of geometric forms, sleek lines, and bold contrasts, the design captures the enduring philosophy that less is more.
Expertly crafted in luminous 18K white gold, the necklace features dramatic onyx elements paired with luminous cultured pearls, creating a compelling interplay of structure and softness. The composition is enriched with 15 brown diamonds totaling 4.27 carats, complemented by 8 baguette-cut diamonds totaling 1.36 carats and 647 brilliant-cut diamonds totaling 11.07 carats. The dynamic mix of diamond cuts and tones enhances the architectural rhythm of the design, resulting in a powerful yet elegant high jewelry statement that exemplifies Cartier’s exceptional mastery of form and material.
