Vintage 18ct Two-Tone Gold Untreated Zambian Emerald Sugarloaf Ring

A boldly architectural vintage ring in 18ct two-tone gold, set with a 1.5 carat untreated Zambian emerald in the sugarloaf cabochon cut — a high-domed, square-cornered form that draws the eye immediately and showcases the depth of colour that Zambian stones are prized for. The emerald is a rich, vivid green with the characteristic slight blue undertone of Zambian origin, and the absence of treatment is a meaningful distinction in a market where the vast majority of emeralds are clarity-enhanced. The setting frames the stone between bold parallel yellow gold rails against a darker patinated gold shank, a combination that gives the ring a strong, graphic quality that feels entirely at home in the 1970s Italian design tradition.

The ring is stamped 18ct, weighs 11.09 grams, and is a size J. Condition is excellent. For the collector who wants a serious emerald in a setting with genuine character, this is a rare find.
