Men's Black Onyx and Diamond/CZ Accent Ring

The item is a men's-style ring, likely made of white gold, platinum, or sterling silver, featuring a central black onyx inlay and accenting clear stones, possibly diamonds or cubic zirconia. The ring has a rectangular-shaped bezel setting for the black onyx, which appears to be polished and free of significant scratches or chips from the visible angle. Flanking the central onyx are channels or rows of small, round, brilliant-cut clear stones, with approximately five stones visible on each side, set flush or prong-set in a low profile. The metal band is thick and substantial, characteristic of a gentleman's ring or a signet ring style, exhibiting a bright, reflective finish. There are no visible maker's marks or hallmarks in the provided image, so the exact metal composition and stone type cannot be definitively determined without closer inspection. The overall condition appears good, with no obvious signs of heavy wear, tarnish, or significant scratches on the visible surfaces, suggesting it has been well-maintained or is relatively new. The design suggests a contemporary or classic style, likely from the late 20th century or early 21st century. The craftsmanship appears to be of decent quality, with the stones well-set and the metal work smooth.
