Modernist Bypass Ring with Green Cabochon Stone

This item is a ring featuring a distinctive contemporary or mid-century modern design. It comprises a polished, silvery-colored metal, likely sterling silver or white gold, formed into a fluid, asymmetrical bypass style band. The band appears to coil around a central, spherical, dark green cabochon stone. The stone itself exhibits a smooth, uninterrupted surface without visible facets, consistent with materials like malachite or jade, or possibly a polished glass or synthetic stone imitating them. Its color is a deep, rich green. The metalwork forms an elegant, organic shape, where one end of the band wraps around the stone and the other end appears to meet or cross over it, creating a visual flow. The surface of the metal shows a high shine, indicating a polished finish, though some minor surface wear or light scratches might be present, typical of a used piece. No distinct hallmarks, maker's marks, or signatures are discernible from the image; such details would likely be found on the interior of the band. The overall condition appears to be good, with no obvious major damage, cracks, or repairs visible. The simplicity of the setting highlights the central stone, suggesting a focus on artistic form rather than elaborate ornamentation. Given the aesthetic, it likely dates from the mid to late 20th century, consistent with the 'antique' context provided, though 'vintage' might be a more precise descriptor for this period.
