Created by Tiffany & Co. in 1910, this platinum ring centers a 1.88-carat step-cut diamond of exceptional D color and VS1 clarity. The elongated geometric stone is held in a finely constructed setting, its open gallery and diamond-set shoulders introducing light from the sides while preserving the clarity of the central silhouette. Rather than the scintillation of a brilliant cut, the step-cut diamond reveals itself through broad, lucid planes—a quieter, more deliberate play of reflection particularly suited to the restrained platinum setting.

Dating to the Edwardian period, the ring captures a moment when platinum allowed jewelers to create increasingly refined, light-filled settings around important diamonds. Tiffany & Co. was central to this evolution in American jewelry, and here the delicacy of the mounting provides an elegant counterpoint to the strength and purity of the center stone. At 4.3 grams, the ring retains an airy appearance while remaining beautifully resolved in its construction.

A diamond of extraordinary whiteness, framed with little more than platinum, proportion, and light.
