Art Deco Platinum & 18kt Gold Ring with Colombian Emerald and Old Cut Diamonds, Circa 1920s

A captivating Art Deco ring from the 1920s, beautifully handcrafted in platinum and 18kt gold. The design captures the architectural precision and glamour that defined the Art Deco era — bold geometry softened by fine craftsmanship.

At its centre sits a vivid natural Colombian emerald of exceptional green, framed above and below by two bright old European-cut diamonds. Surrounding these are smaller pavé-set diamonds arranged in a stepped, geometric outline that shimmers with every movement. The platinum top contrasts beautifully with the warm gold beneath, giving the ring both strength and subtle warmth.
