Months of searching. One perfect stone.

Finally back, the Oval Leia is one of our hardest rings to replace. True antique oval diamonds are rare, and finding one worthy of the design can take months. We wait patiently for stones with extraordinary beauty and character, never settling until the right one appears.

Inspired by an Edwardian ring from our archive, our latest Oval Leia centers a rare 2.18 carat antique oval diamond surrounded by a halo of antique old European cut diamonds. The largest oval center we’ve ever offered in this setting, it delivers striking finger coverage while maintaining the low, comfortable wearability that has made the design a favorite.

One For You 2.07 centers an antique old mine cut diamond with broad, chunky faceting and a softly squared outline characteristic of early hand cut diamonds. Originally designed for the softer glow of candlelit interiors, the diamond displays a quieter, more romantic brilliance with large flashes of light unique to antique cuts. Its subtle fancy light brown tone reads warm rather than flashy, the kind of diamond appreciated by those who truly know antique stones. Set in an 18k yellow gold Georgian inspired cut-down collet mounting with a button back style profile, the ring sits gently elevated while maintaining a low, highly wearable feel. In an era of AI precision and perfect calibration, these antique diamonds remain impossible to replicate, each one individually hand cut and increasingly rare.
