A 1920s Art Deco Diamond and Onyx Ring with Crisp Geometric Design

A striking Art Deco ring from the 1920s, this piece is centred with diamonds framed by sharply cut onyx, creating the bold geometry so loved in the period. The elongated plaque, fine millegrain detail, and airy openwork gallery give it both strength and elegance. There is something especially pleasing in the balance of its design, crisp and graphic, yet quietly refined.
