Vintage Filigree Brooch with Iridescent and Garnet-toned Rhinestones

This is a vintage brooch characterized by its intricate filigree design and ornate embellishments. The item appears to be crafted from a base metal with a brass or antiqued gold-tone finish, exhibiting a rich, slightly aged patina that adds to its vintage aesthetic. The construction features a delicate openwork pattern, possibly stamped or cast metal, formed into swirling floral or leafy motifs. Embedded within this filigree are numerous rhinestones. There are several larger, round faceted stones that appear to be a deep garnet or reddish-brown hue. Interspersed among these are smaller, round iridescent rhinestones, possibly aurora borealis-coated, which display a captivating play of colors including blues, greens, and pinks when catching the light. The arrangement of the stones is asymmetrical but balanced, contributing to a sense of organic elegance. The overall shape of the brooch is circular with scalloped edges formed by the filigree. There are no visible maker's marks or signatures from the provided image, suggesting it may be unsigned costume jewelry. The condition appears good for its age, with all stones present and no obvious signs of significant damage or repairs. Minor wear to the metal finish consistent with age is likely. This piece is indicative of mid-20th-century costume jewelry, possibly dating from the 1940s to 1960s, known for its elaborate designs and use of vibrant rhinestones.
