Art Deco Style Marcasite and Amethyst Paste Pendant

This necklace features a teardrop-shaped Art Deco-inspired pendant characterized by strong geometric lines and symmetry. At its center is a large, emerald-cut violet-purple stone, likely an amethyst-colored paste or synthetic crystal, measuring approximately 12x10mm. The central stone is held in a bezel setting within an ornate openwork frame. This frame is constructed from a silver-toned base metal, possibly sterling silver, featuring numerous small, rose-cut marcasite stones bead-set throughout the structure. These marcasites provide a characteristic metallic, subtle glitter against the dark, oxidized metal background. The pendant exhibits a vertical geometric arrangement with tiered side elements and a decorative articulated bail also set with marcasites. It is suspended from a simple fine-link curb chain. The condition appears fair to good with a notable aged patina and darkening of the metal, particularly in the recessed areas (milgrain detailing). There is visible surface wear and slight dulling on the central stone facets consistent with use. The piece reflects the geometric aesthetics of the 1920s-30s but is likely a vintage reproduction from the mid-to-late 20th century. No clear manufacturer stamps or metal purity hallmarks are visible in the primary view.
