Large Oval Smoky Quartz and Diamond Gold Cocktail Ring

This is a substantial vintage cocktail ring featuring a large, oval-faceted smoky quartz as the primary focal point. The central stone is a translucent, deep chocolate brown color and is held in a decorative yellow gold setting. The mounting is intricately designed with organic, leaf-like gold prongs that wrap around the edges of the gemstone. Interspersed among these gold elements are four small, round brilliant-cut colorless stones, likely diamonds or high-quality white sapphires, each set in their own individual prongs to provide a sparkling contrast to the dark quartz. The gold exhibits a warm, high-carat luster, though there are visible signs of wear including surface scratches and a light patina consistent with age. The craftsmanship suggests a mid-20th-century origins, possibly from the 1960s or 70s, characterized by the bold, brutalist-adjacent organic metalwork. While no specific maker's mark is visible in the photograph, the weight and complexity of the setting indicate a high level of jewelry design. The central quartz stone appears to have minor facet wear and some internal inclusions typical of the natural mineral.
