Vintage Onyx and Diamond Bar Ring

Onyx bar rings are firmly linked to the Art Deco era. Bar rings, horizontal plaques, and step-cut geometries mirrored the modern industrial architecture of the time. Art Deco jewelry famously paired the stark midnight-black of flat-cut onyx with the brilliant sparkle of white diamonds.

This ring has a striking presence on the hand. It is a beautiful evening statement ring that is durable enough to be worn daily.
