Silver-Toned Ring with Dark Gemstone and Filigree Accents

The item is a ring, appearing to be crafted from a silver-toned metal, possibly sterling silver or white gold, given its luster and visible tarnishing in some areas. The band is a relatively flat and wide design, with visible markings or perhaps filigree etching on the inner surface, though these are not clearly discernible beyond being some form of text or pattern. The outer surface of the band shows some wear, particularly around the edges, suggesting regular use. The focal point of the ring is a central, bezel-set, round gemstone that appears black or very dark in color, consistent with onyx or a dark sapphire, though without further testing, the exact stone cannot be determined. This central stone is flanked by decorative metalwork, possibly a leaf or vine motif, which adds an organic, almost Art Nouveau-inspired flair to the design. The metalwork surrounding the stone shows signs of patina and slight discoloration, indicating age and handling. The craftsmanship appears to be of decent quality, with the bezel setting of the stone looking secure. There are no obvious signs of major damage or repairs, but the overall condition suggests it is a used piece, likely an older item given the design elements and natural wear patterns.
