18k Yellow Gold Emerald-Cut Amethyst Statement Ring

This is a substantial cocktail-style statement ring featuring a large, emerald-cut natural amethyst center stone. The amethyst exhibits a medium-to-deep royal purple hue with visible color zoning, characteristic of natural quartz. It is securely held by four thick, elongated double prongs in a high-profile basket setting. The ring is constructed of 18k yellow gold, identifiable by its rich, deep yellow luster. The shank is highly decorative, featuring a multi-strand openwork design with textured detailing, including rope-style twists and polished vertical bars that taper toward the base. The overall style is reminiscent of the mid-20th century, specifically the Retro period (circa 1940s-1950s), known for bold, architectural gold work and large semi-precious gemstones. In terms of condition, the metal shows a soft patina consistent with age and light surface micro-scratches. The amethyst appears to have minor facet-edge wear and a slight chip or abrasion near the lower-left prong. The craftsmanship is high-quality, indicated by the structural complexity of the gallery and the symmetry of the heavy prongs. While specific maker's marks are not visible in the photo, the design suggests custom or boutique benchwork typical of high-end vintage jewelry.
