Ornate Gold Filigree Ring with Oval Dark Blue/Teal Gemstone

This item is an antique or vintage cocktail ring, likely constructed from a gold alloy, given its distinct yellow metallic sheen and apparent age. The main feature is an oval-cut gemstone, which appears to be a dark blue or teal color, possibly a sapphire, tourmaline, or even simulated glass, set within a bezel or partial bezel setting. The intricate design of the ring's head is highly ornate, featuring an openwork filigree pattern with numerous small, spherical, bead-like embellishments along the outer edge. These beads create a textured, halo-like border around the central setting. Flanking the central gemstone are swirling, curvilinear motifs, possibly indicative of Art Nouveau or Edwardian stylistic influences, though the overall design suggests a Victorian revival or a 1920s-1940s period piece. The gold appears to have a rich, warm patina, consistent with age and minimal polishing, which enhances the antique aesthetic. There are no immediately visible signs of heavy damage, such as missing beads, significant dents, or bent metal, though close inspection would be needed to detect any tiny scratches or minor wear consistent with use. The quality of craftsmanship appears to be good, with attention to detail in the filigree and beadwork, indicating skilled artisanry rather than mass production. The specific type of metal (e.g., 10k, 14k, 18k gold) or the exact nature of the gemstone cannot be determined from the image alone, but these are crucial details for a full appraisal.
