Vintage-Style Silver Ring with Black Cabochon Stone

This is a vintage-style ring, likely crafted from silver or a silver-plated base metal, given its tarnished appearance and matte, somewhat darkened finish. The ring features an oval-shaped, smooth, bezel-set black cabochon stone at its center, which could be onyx, obsidian, or black tourmaline, among other possibilities. The total size appears to be suitable for a finger, likely a size 6-8, based on typical ring dimensions. The ring's shoulders are split and ornamented with intricate, possibly filigree or granulation work, featuring small spherical elements (beading) and stylized foliate or scroll motifs. There are small cut-outs on the shoulders creating an openwork effect, adding to its decorative appeal. The band itself is relatively thin and simple where it connects at the back, suggesting a focus on the decorative top. Visible condition issues include significant tarnish over most of the metal surface, which lends an aged patina but also obscures finer details or potential hallmarks. No specific maker's marks or signatures are discernable from the image. The craftsmanship appears to be reasonably good, with symmetrical design elements, but the overall presentation, including the stone setting, does not suggest high-end, precision manufacturing. Its aesthetic points towards a late 19th to early 20th-century design influence, possibly Art Nouveau or Edwardian revival, or it could be a more modern piece styled to evoke that period. The stone itself appears intact with no visible chips or cracks. The bezel setting looks secure. This piece has a handcrafted or artisan feel.
