Cartier Trinity 18k Three Tone Gold Large Model Band Ring Size 48

Cartier's Trinity has stayed essentially unchanged since 1924, and this large model shows exactly why — three bands of 18k gold, rose, yellow, and white, interlocked so they roll and shift independently on the finger rather than sitting fixed in place. The Cartier signature is engraved along the rose gold band, understated against the polish, while "Au 750" marks the gold purity on the interior. No stones, no embellishment beyond the three-tone contrast itself; the design has always been the point.
