Vintage Oval Moss Agate or Jasper Pendant in Silver-Tone Bezel

This item is an oval-shaped jewelry pendant featuring a large cabochon-cut semi-precious stone, likely a variety of Moss Agate or Ocean Jasper. The stone displays a complex internal matrix with deep forest green, murky teal, and sandy ochre-yellow inclusions, typical of silicated minerals. The stone is set in an ornate, silver-colored metal frame (likely sterling silver or a base metal alloy). The frame features a decorative border consisting of an inner rope-style twist and an outer scalloped or 'dog tooth' edge with small rounded protrusions. A small integrated bail loop is located at the top for suspension from a chain. Regarding condition, the metal shows significant dark oxidization and patina throughout the crevices of the decorative border, which is consistent with age and typical of vintage silver-tone jewelry. The stone appears to have a smooth, polished surface with no significant surface fractures or chips visible in the image. The craftsmanship suggests a mid-20th-century artisan or Southwestern style production. There are no maker's marks visible on the front, but the heavy patina suggests it has been handled over many decades. The overall construction is robust, showcasing traditional bezel-setting techniques common in folk or costume jewelry designs.
