Vintage Yellow Gold and Round-Cut Pink Quartz Solitaire Ring

This item is a vintage-style solitaire ring featuring a large, round-cut pink gemstone, likely pink quartz or rose de france amethyst, set in a yellow gold mounting. The gemstone exhibits a soft, translucent pink hue with visible faceting that suggests a standard brilliant or rose cut. The focal stone is held securely by a decorative basket-style setting. The shoulders of the ring transition into an intricate filigree or openwork gallery design, which is characteristic of jewelry from the mid-20th century, possibly the Retro or early Post-War period (circa 1940s-1950s). The metal appears to be a high-karat yellow gold based on its rich color tone. Regarding condition, the metal shows a mild aged patina and minor surface scratches consistent with regular wear, while the gemstone appears intact with no major chips visible from the primary angle. The craftsmanship displays fine detail in the openwork undergallery, providing structural integrity while allowing light to pass through the stone. No specific maker's marks or fineness stamps are visible in the provided image.
