Vintage Sterling Silver and Marcasite Oval Locket or Pendant

This is a vintage oval-shaped pendant or locket, likely crafted from sterling silver based on the color and oxidation patterns. The design features a central polished, domed silver cabochon surrounded by an intricate border set with numerous rose-cut marcasite stones. These stones are arranged in a floral or beaded cluster pattern that provides a dark, metallic sparkle characteristic of early to mid-20th-century jewelry. The bail at the top is also decorated with three marcasite stones, ensuring design continuity. The piece exhibits an Art Deco influence but is likely a mid-century revival piece (circa 1940s-1960s). Physically, the item shows a significant amount of superficial surface scratching and micro-abrasions on the central polished dome, consistent with long-term wear. There is a noticeable dark patina in the recessed areas (oxidation), which helps to highlight the detail of the metalwork. All marcasite stones appear to be intact and original. While no maker's mark is visible from this angle, the construction suggests a cast silver frame with hand-set pavé stones. The overall craftsmanship is of good quality, typical of mass-produced silver jewelry of its era.
