Mid-Century Vintage Rhinestone Bracelet with Marquise Aquamarine Glass Focal

This is a mid-century vintage costume jewelry bracelet, likely dating from the 1950s or 1960s. It features a triple-row design of clear, round, foil-backed rhinestones set in a silver-toned base metal, possibly rhodium-plated pot metal, which was common for the era. The central focal point consists of a single, larger marquise-cut glass stone in a vibrant aquamarine blue, held by a four-prong setting. The construction uses individual cup settings joined by links, allowing for flexibility around the wrist. The clear stones exhibit varying degrees of age-related darkening or 'yellowing,' indicative of foil degradation over time. There is noticeable surface wear and oxidation on the metal prongs and settings. The central blue stone appears well-preserved with a bright clarity. The bracelet's design is typical of mid-market vintage costume jewelry brands like Coro, Trifari, or Weiss, though no maker's mark is visible in the provided image. Its overall condition is fair to good, showing signs of age that contribute to its vintage character while highlighting the need for careful handling to prevent further foil loss in the rhinestones.
