Vintage Diamond Engagement/Cocktail Ring

This item is a vintage ring, likely an engagement or cocktail ring, featuring a central faceted clear gemstone, most probably a diamond, set within an ornate, dome-shaped setting. The ring is constructed from a white-colored metal, appearing to be white gold or platinum, judging by its luster and the common materials used in rings of this style. The design incorporates intricate filigree and openwork detailing around the central stone, showcasing delicate scrollwork or floral motifs along the shoulders and sides of the ring. This detailed craftsmanship suggests it could date from the Edwardian, Art Deco, or early Retro periods (approximately 1900-1940s), characterized by their love for intricate metalwork and milgrain edges, although specific dating would require closer examination of the setting techniques and stone cut. The central stone appears to be a round brilliant cut or an old mine cut, depending on its age and facet pattern, which is not entirely clear from the image. Surrounding the central stone, there might be smaller accent stones or milgrain detailing, contributing to its overall sparkle and decorative appeal. The visible condition suggests some wear consistent with its age, possibly minor surface scratches on the metal and stone, and a slight patina which is common for antique jewelry. No specific maker's marks or signatures are discernible from the provided image. The quality of craftsmanship appears high, indicated by the fine details in the metalwork. The ring has a substantial, domed profile, making it a prominent piece on the finger. The band's visible part also features continuation of the decorative elements, suggesting a holistic design approach.
