Vintage Gold-Tone Sunburst Brooch with Faux Pink Stone and Simulated Pearls

This is a vintage-style sunburst or starburst costume brooch. Centrally, it features a large, oval, high-domed cabochon of a speckled pink translucent material, likely glass or acrylic intended to mimic pink mottled stone like rhodochrosite. The center stone is held in place by numerous small, dark-colored metal prongs. Surrounding this central focal point are eight decorative gold-tone metal arms. Each arm consists of a textured, openwork bow or filigree motif, capped with a small round pearl-like bead. These smaller beads alternate between a pure white luster and a pale pinkish-white hue, all held in four-prong settings. The metal appears to be a textured gold over base metal. In terms of condition, there is notable green oxidation (verdigris) visible around several of the prongs securing the central stone, which indicates moisture exposure and age. The gold plating shows light surface wear, consistent with mid-20th-century costume jewelry, likely dating from the 1960s or 1970s. No maker's mark is visible from the front view, though it follows a common design language used by manufacturers like Sarah Coventry or Trifari for affordable fashion accessories of that era.
