Oval Black Onyx Ring in Silver Setting

This item is a ring featuring a prominent oval-shaped black cabochon, likely onyx, set within a simple bezel mounting. The stone exhibits a high-gloss, reflective surface with a deep, uniform black saturation and no visible inclusions on the crown. The setting appears to be made of a silver-toned metal, possibly sterling silver based on the color and surface wear. The bezel is relatively thick and surrounds the stone securely. The ring's shank is split or features parallel bands near the shoulder, suggesting a mid-century or modern minimalist design. The metal displays a mild patina and light surface scratches consistent with age and gentle wear, particularly along the rim of the bezel. No visible maker's marks or hallmarks are immediately apparent in the image, but the construction indicates a solid level of craftsmanship typical of mid-20th-century costume or studio jewelry. The overall condition is good, with the stone appearing chip-free and the setting retaining its structural integrity. This style is characteristic of the 1960s or 1970s modernist movement.
