Vintage Filigree Turquoise Rhinestone Brooch Pin

This is a vintage brooch or pin, likely dating from the mid-20th century, characterized by its intricate filigree work and a vibrant display of turquoise-colored rhinestones. The item consists of two main sections connected by two sturdy brass-toned chains. The top section is a smaller, ornate brass or gold-tone metal piece, featuring a central cluster of five small round turquoise rhinestones set within a floral or foliate design. This upper element is flanked by two small sculpted leaves. Below this, two robust curb chains descend, connecting to a larger, more elaborate lower pendant. This main body is a circular, multi-layered filigree piece, heavily adorned with a floral and leaf motif. At its center is a prominent oval-cut turquoise rhinestone, surrounded by nine smaller round turquoise rhinestones. The smaller stones are set in individual prong settings, while the central oval stone appears to be bezel-set, though it's difficult to confirm definitively from the image. The metalwork exhibits a warm, aged patina consistent with brass or a gold-tone alloy, showing some darkening in the deeper recesses, which accentuates the relief of the design. There are no immediately obvious signs of damage such as missing stones or broken chains, though typical wear from age and handling is present in the form of surface scratches and tarnishing on the metal. The overall construction suggests a good level of craftsmanship for costume jewelry of its era, with a focus on decorative detail and a striking color contrast between the metal and the blue stones. The back, which is not visible, would typically feature a pin mechanism for attachment. The style is reminiscent of Victorian or Edwardian revival jewelry, specifically the 1940s-1960s period.
