Vintage Silver-Tone Ornate Bangle with Blue Marbled Inlay

This item is a vintage-style bangle bracelet, likely constructed from a silver-tone base metal, possibly an alloy or plated material, given its slightly dulled luster and the visible wear in some areas. The bracelet features an ornate design with prominent hexagonal or octagonal panels that house a striking blue marbled inlay. The inlay material appears to be a type of resin or plastic, characterized by its glossy finish and irregular patterns of bright blue and darker, almost black, swirls, mimicking a natural stone like turquoise or lapis lazuli but with a distinctly artificial uniformity. Each inlaid panel is set within an intricately detailed frame, featuring a rope-like border and an additional inner texture that looks like fine filigree or granulation. The connecting links between these panels are also highly decorative, exhibiting an openwork, lattice-like pattern. The overall construction suggests a hinged or elasticized design to allow for easy wearing, typical of bangle bracelets that are not solid. Visible condition issues include some surface wear, minor scratches on the blue inlay, and a slight darkening or patina on the metalwork, consistent with age and use. The craftsmanship is indicative of costume jewelry from the mid to late 20th century, seeking to emulate more expensive pieces with its detailed metalwork and simulated gemstones. There are no discernible maker's marks or signatures visible from the provided images, which is common for mass-produced vintage costume jewelry.
