Platinum Deco Diamond and Onyx Ring

A striking Art Deco-style ring, set with a faceted onyx plaque mounted in platinum. At the centre sits a bright, natural diamond, bezel set for security and contrast against the rich black ground. The shoulders of the mount are detailed with subtle engraved decoration, adding refinement to the geometric design.

This ring embodies the elegance of the early 20th century, where bold monochrome combinations of onyx and diamond were highly fashionable.
