1950s Cartier Sapphire and Diamond Three Stone Ring

A disciplined mid century three stone ring that reflects the unmistakable design language of Cartier, where proportion, restraint, and precision define the design. The composition is architectural and intentional, emphasizing balance and clarity rather than ornament. Crafted in platinum, the ring is set with two unheated Burmese sapphires totaling approximately 0.52 carats, flanked by carré cut diamonds totaling approximately 0.59 carats, graded approximately F color and VS clarity. The crisp geometry of the diamonds and the saturated blue of the sapphires create a controlled contrast that Cartier favored during this period, highlighting structure and material over excess. Signed Cartier, stamped 900 platinum and bearing a serial number. Refined, exacting, and quietly authoritative, it is a clear expression of Cartier’s mid century craftsmanship and enduring design philosophy. Approximate size 6
