Vintage Emerald-Colored Glass or Resin Pendant

This item is a small, rectangular pendant featuring a vibrant, emerald-green translucent centerpiece. The central stone appears to be either faceted glass or a molded resin, set within a simple, dark-toned metal frame that exhibits significant age-related patina or oxidation, suggesting it may be silver-toned base metal or perhaps tarnished sterling silver. The pendant measures approximately 1 to 1.5 centimeters in length. It is held by a four-prong setting visible at the corners. Attached to the top is a small jump ring connected to a larger, triangular bail intended for a chain. The bail shows a matte, darkened finish consistent with mid-20th-century costume jewelry. There are no immediate maker's marks visible in the photograph, though the construction is typical of mass-produced vintage accessories from the 1950s to 1970s. The condition shows light surface wear on the 'stone' and heavy tarnishing on the metallic components, adding to its vintage character. The green insert has an internal texture that catches the light, giving it a depth similar to natural beryl, though its regularity suggests a synthetic origin. The craftsmanship is functional rather than high-end, indicative of everyday wear jewelry from its era.
