Vintage Turquoise and Silver-Tone Brooch

This is a vintage brooch featuring a striking combination of turquoise-colored stones and silver-tone metalwork. The brooch has a circular, almost floral or star-like shape, with an approximate diameter of 1.5 to 2 inches. The base metal appears to be a silver-tone alloy, possibly pewter or a plated metal, exhibiting an antiqued or oxidized finish to highlight the embossed and filigree details. The overall design suggests a bohemian, Southwestern, or possibly even a Victorian revival aesthetic, popular in the mid-20th century. The central element is a large, domed, round turquoise-colored cabochon stone, likely a polymer or treated, reconstituted stone given the uniform color and internal matrix patterns. This central stone is surrounded by a silver-tone filigree setting resembling petals or scrollwork, further accented by small, round, raised gold-tone dots or beads that contrast with the silver. Surrounding this central motif are three larger, irregularly shaped, flat turquoise-colored stones, often referred to as 'cabochons' or 'tiles,' which form a triangular or fan-like arrangement, separated by sections of the textured silver-tone base. These three stones also exhibit a mottled turquoise color with hints of brown or reddish matrix, suggesting natural turquoise or a good imitation. Around the outer perimeter of the brooch are six smaller, spherical, sky-blue stones, which appear to be either polished beads or cabochons, attached to the silver-tone frame. The silver-tone frame itself is highly decorative, featuring a beaded edge and ornate, scrolling patterns with a slightly raised, embossed texture. The 'vintage' context suggests an age ranging from the 1950s to the 1980s. The condition appears to be good for its age, with visible patina on the metalwork and minor wear appropriate for a used vintage item. No specific maker's marks or signatures are visible in the provided image, which is common for many costume jewelry pieces of this era. The craftsmanship, while not fine jewelry grade, is consistent with quality vintage costume jewelry, showing intricate detailing.
