Yellow Gold and Black Onyx Cabochon Ring

The item is a statement ring featuring a prominent, elongated oval-shaped cabochon of polished black stone, likely onyx, set within a highly polished yellow metal band. The stone has a smooth, domed surface, which exhibits a strong, mirror-like reflection, indicative of excellent polishing and a hard, dense material. The black color is deep and consistent, with no visible inclusions or imperfections on its surface. The yellow metal, appearing to be gold due to its rich luster and color, forms a substantial and sculptural band. It features a wide, flared design that tapers towards the base, with the stone bezel-set into the widest part of mount. The craftsmanship appears to be of high quality, with seamless joins and a flawless, reflective finish on the metal. There are no visible condition issues such as scratches, dents, or chips on either the metal or the stone, suggesting it is either very well-preserved or relatively new. No maker's marks or signatures are discernible from the provided image, but the clean lines and bold presence suggest a modern or mid-century design aesthetic. The ring has a substantial feel, indicating a good weight of metal, contributing to its overall quality.
