Vintage Intaglio Glass Cameo Pendant Necklace

This vintage-style jewelry piece features an oval-shaped, clear intaglio glass cameo suspended from a medium-weight rope chain. The pendant highlights a central reverse-carved (intaglio) figure of a classical maiden or goddess, rendered in a frosted white finish that creates a three-dimensional effect against the transparent glass background. The glass is set within an elaborate, silver-toned metal frame characterized by a twisted rope or braided wire border. The chain appears to be a matching silver-toned base metal with a tight spiral rope construction, secured with a standard spring ring clasp. Based on the aesthetic and construction, it is likely a mid-to-late 20th-century costume jewelry piece. Condition-wise, the glass shows some internal yellowish discoloration or adhesive oxidation near the bottom edge of the intaglio carving, and there is minor surface wear on the metal frame. No visible maker's marks are present in the image, but the craftsmanship is consistent with popular vintage costume accessory brands like Coro or Trifari.
