Oval Hematite or Onyx Cabochon Ring

This item is a decorative finger ring featuring a prominent oval-shaped cabochon gemstone, which appears to be either hematite or black onyx. The stone exhibits a high-luster, reflective surface and deep black color, set within a textured or pavé-style bezel. The setting surrounds the central stone with a decorative border that likely contains small inset white stones (merit further testing to determine if they are diamonds, marcasite, or clear quartz) or a beaded metalwork pattern. The metal of the band and setting appears to be silver-toned, possibly sterling silver or a white gold alloy, though no hallmarks are visible from this orientation. In terms of condition, the piece shows surface-level wear consistent with age, including minor scuffs on the gem and a darkened patina within the recessed areas of the setting, which is common in vintage jewelry. The design aesthetic is reminiscent of the mid-20th century Art Deco Revival or late Victorian mourning styles, suggesting a mid-to-late 20th-century manufacture. The craftsmanship shows a cohesive integration of the gemstone into the mounting, indicating a good level of commercial bench jewelry quality.
