Vintage-Style Sunburst Turquoise Cabochon Brooch

This circular sunburst brooch features a multi-tiered radial design constructed from darkened, antique-finished brass or base metal. The piece is set with numerous round, turquoise-colored glass or resin cabochons. Each stone is held within a small bezel or prong setting, arranged in concentric circles that emanate from a central large stone surrounded by smaller petals. The metalwork consists of thin radial spokes connecting the inner and outer rings, creating a sophisticated openwork or filigree appearance. The stones possess a soft, milky opacity, characteristic of faux turquoise or opalite glass, with several displaying subtle iridescent flashes that suggest an Aurora Borealis coating. The overall construction appears to be high-quality costume jewelry, likely dating from the mid-to-late 20th century or a modern vintage reproduction. The condition is excellent with no missing stones; however, there is visible darkening on the metal prongs and spokes, which may be intentional patination or natural oxidation over time. No visible maker's marks are present on the front, but the piece carries a white paper price tag, suggesting it is a retail or resale item.
