Filigree Necklace with Blue Cabochons and Central Medallion

This is a vintage-style necklace, likely crafted from silver or a silver-toned metal, characterized by intricate filigree work and a symmetrical design. The necklace features a series of six circular settings, each holding a vibrant blue cabochon stone. These stones appear to be either turquoise, lapis lazuli, or a synthetic imitation, and have a smooth, polished surface with no visible facets. The settings themselves are surrounded by delicate, openwork filigree, creating a floral or sunburst motif. Five of these cabochon settings are distributed along the upper portion of the necklace, with two on each side leading towards a central drop. The central element of the necklace comprises a larger, prominent circular medallion from which a single cabochon-set drop dangles. The central medallion features an image or design rendered in gold and green tones, possibly depicting an abstract pattern or a stylized figure, though the details are not clearly discernible from the image resolution. The filigree work on this central piece is notably finer and more elaborate. The chain itself is a delicate, possibly rolo or cable link, suggesting a lightweight construction. The clasp appears to be a spring ring clasp, a common finding for necklaces. The overall condition shows a slight darkening or tarnishing consistent with age and exposure, suggesting either silver with natural patina or a base metal that has discolored over time. There are no obvious signs of significant damage, repairs, or missing components. The craftsmanship, particularly the filigree, indicates a handmade or semi-handmade origin, typical of ethnic or bohemian jewelry styles, possibly from the mid-20th century or earlier due to the traditional design.
