Antique Art Deco Checkerboard Cut Onyx Diamond Ring In 18ct Yellow Gold

This beautiful Art Deco piece features a 0.20ct old-cut diamond set at the centre of a striking checkerboard-cut black onyx panel. The geometric design is everything I love about the Deco era—bold, elegant, and effortlessly wearable nearly a century later.

Crafted in 18ct gold, it’s the kind of ring that looks just as good stacked with modern bands as it does worn on its own. The diamond catches the light beautifully against the deep black onyx, giving it that timeless black-and-white contrast that never goes out of style.

A genuinely special antique with character, craftsmanship, and a design that’s becoming harder to find.
