Vintage Black and Clear Rhinestone Cameo Brooch

This is an antique or vintage cameo brooch, featuring a central oval-shaped cameo set within an ornate, multi-gemstone frame. The cameo itself depicts the profile of a woman's head and shoulders, carved in a light grey material, possibly a form of plastic, resin, or molded glass, against a darker, possibly black, background. The carving detail on the woman's hair and drapery is visible, suggesting a certain level of craftsmanship. The outer frame is composed of numerous faceted rhinestones and larger black glass stones, arranged in a scalloped or floral pattern. The black stones are predominantly marquise cuts and round cuts, creating a striking contrast with the clear rhinestones, which appear to be round or cushion cut. The metal setting supporting these stones is silver-toned, likely base metal given the era, and shows some signs of darkening or patina in the crevices, indicating age. There might be some wear on the facets of the rhinestones, consistent with an item of this age. The overall construction appears sturdy, with stones set securely, though specific setting types are not entirely clear from the image. This piece is likely from the Art Deco to Mid-Century period, possibly 1920s-1950s, given the style of the cameo and the use of rhinestones and glass. The craftsmanship, while not fine jewelry grade, indicates a well-made costume piece designed for decorative impact.
