Vintage Rhinestone Collar Choker Necklace

This is a vintage collar-style choker necklace featuring a continuous row of circular, bead-like segments. Each segment is prominently encrusted with clear, round-cut rhinestones set in a pave or buttercup style. The necklace appears to be constructed from a base metal, likely brass or pot metal, with a silver-tone or rhodium plating that shows significant surface oxidation and darkening, resulting in a matte, pewter-like patina. The design is characteristic of the mid-20th century, likely dating from the 1940s to 1950s, a period popular for such 'rivière' or 'bolero' style costume jewelry. The individual stones appear to be glass paste and are deeply set into the metal casings. In terms of condition, there is visible tarnish across the metal surfaces and some stones appear slightly yellowed or dulled, often referred to as 'greying' in vintage stones, which is typical for items of this age where the foil backing has begun to degrade. The piece exhibits high-density stone placement, indicating a quality level typical of higher-end costume jewelry houses of the era. No maker's marks are immediately visible in the forward-facing photo, but the robust construction and uniform stone settings point toward a piece designed for durability and evening wear.
