Vintage Filigree Turquoise Cabochon Brooch

This is a multifaceted vintage brooch featuring a large, round faux-turquoise cabochon centerpiece. The cabochon displays a deep teal coloration with characteristic dark veining, held within a multi-layered metal framework. The design incorporates intricate silver-tone filigree and openwork borders, including a scalloped inner bezel and a wide, floral-stamped circular plate. The outer perimeter is defined by decorative open-back scrolls and raised metal lugs, suggesting a mid-20th-century costume jewelry aesthetic, likely from the 1960s or 1970s. The construction appears to be a mixed-metal assembly with a possible antique silver-wash finish. Condition-wise, the piece shows moderate surface patina and darkening in the crevices of the filigree, which is typical for its age. There are no visible chips to the central stone, though the metal components show slight wear on the raised edges. The overall craftsmanship indicates a mass-produced but high-quality decorative piece, potentially designed in a Western or Revivalist style. No manufacturer's mark is visible from the front view, but the complexity of the stamping suggests a professional jeweler's production.
