Vintage Filigree Turquoise Cabochon Bar Brooch

This is a vintage bar-style brooch featuring a central turquoise cabochon set within an intricate openwork filigree frame. The piece exhibits an oblong, symmetrical shape with lateral wings that incorporate horizontal banding and small beaded or 'granulated' metallic accents. The metal appears to be a gold-tone alloy, possibly brass or gold-plated base metal, showing a significant dark patina particularly in the recessed areas of the design. The central turquoise element is a dome-shaped, teal-green cabochon, likely genuine stone or a high-quality glass imitation common in costume jewelry from the mid-20th century. The construction utilizes a layered 'stacked' look around the central stone, typical of Bohemian or Revivalist styles from the 1940s to 1960s. Condition-wise, the brooch shows moderate surface wear and oxidation consistent with age. There are no visible maker's marks from the top view, and the overall craftsmanship suggests a mass-produced but decorative fashion accessory of its era.
