Vintage-Style Marcasite, Onyx, and Faux Pearl Floral Brooch

This item is a decorative floral-motif brooch, likely crafted from silver-toned metal, possibly sterling silver or a base metal alloy. The central feature is a white, round cabochon bead representing a pearl, which sits at the heart of an intricate multi-layered flower. The design features eight radiating leaf-like petals embellished with pave-set marcasite stones, giving the piece a classic metallic glitter. Interspersed between these textured petals are smooth, polished black stones, likely onyx or black glass, cut in a teardrop or pear shape. The construction utilizes milgrain detailing around the edges of the metalwork, a hallmark of Art Deco or Edwardian revival styles. The item appears to be in good vintage condition with no missing stones visible in the image, though some light tarnishing or patina is evident on the metal surfaces. The arrangement is symmetrical and displays a sophisticated contrast between the matte sparkle of the marcasite, the luster of the central pearl, and the deep sheen of the black accents. Such pieces were popular in the early to mid-20th century, though mass-produced revivals continued through the 1980s. The quality of the setting suggests a mid-market costume jewelry piece or a fine silver accessory depending on the metal purity.
