Italian Silver Art Deco Style Marcasite and Multi-Gemstone Round Pendant

This is a large, circular pendant of Italian origin, crafted from sterling silver featuring a complex Art Deco-inspired design. The piece is heavily embellished with pave-set marcasite stones that impart a dark, metallic luster across the circular face and the decorative bail. At the center is a cluster of multi-colored gemstones including oval-cut rubies and emeralds, arranged in a cruciform or floral motif. The silver exhibits a significant dark patina, which is characteristic of vintage silver and enhances the contrast against the sparkling marcasites. The construction involves a cast silver base with milgrain edging, adding fine texture to the borders. The bail is substantial and tapered, also encrusted with marcasites, allowing for a medium-to-heavy chain. While the provided context mentions onyx, the primary dark sparkle comes from faceted marcasite, which was highly popular in early 20th-century jewelry styles. The piece appears to be in good vintage condition with no visible missing stones, though the silver shows natural oxidation. The craftsmanship suggests a mid-to-late 20th-century production that pays homage to the 1920s aesthetic. It is a bold statement piece combining the cool tones of silver with the deep hues of precious gemstones.
