Vintage-Style Faceted Black Stone Cocktail Ring

This is a substantial vintage-style cocktail ring featuring a prominent oval-shaped, faceted black stone set in an ornate brass or gold-toned metal setting. The stone appears to be either glass, onyx, or another opaque dark gemstone, exhibiting multiple facets that catch the light, though some surface wear or dust is visible. The setting holding the main stone is highly decorative, characterized by a scalloped or beaded edge around the bezel, which suggests intricate craftsmanship, possibly filigree or granulation work. The metal has an aged, tarnished patina, contributing to its vintage aesthetic. The ring's band is visible and appears to be a twisted or braided design, also in the same brassy metal, adding to the overall detailed and period-appropriate look. The size of the stone is quite large relative to the finger it's worn on, indicating it's intended to be a statement piece. No specific maker's marks or signatures are discernible from the image, but the style points towards a Victorian revival, Art Deco revival, or mid-20th century costume jewelry piece. The overall condition shows some expected wear consistent with age, including potential scratches on the stone and tarnish on the metal. This ring exudes a bold, antique charm, ideal for a formal occasion or as a unique accessory.
