Vintage Oval Moonstone-Style Cabochon and Black Marquise Rhinestone Brooch

This is a vintage cluster-style brooch, approximately 1.5 to 2 inches in height, featuring a central large oval cabochon. The central stone exhibits an opalescent, milky-white hue reminiscent of moonstone or glass 'saphiret' variations, set within a gold-tone pronged bezel. Surrounding the center is a rhythmic halo of jet-black marquise-cut rhinestones, each multi-faceted to catch the light. Interspersed at the outer perimeter are smaller, round clear chaton rhinestones that provide a high-contrast sparkle against the black stones. The construction appears to be a tiered metal setting, likely gold-plated brass or pot metal, common in mid-20th-century costume jewelry. The craftsmanship suggests a mid-tier vintage manufacturer from the 1950s or 1960s, a period popular for this monochromatic and 'white fire' aesthetic. Condition-wise, the stones appear to be intact with no visible chips, though the central cabochon shows some minor surface scuffing consistent with age. There is slight dullness to some of the clear rhinestones, which may indicate aging of the foil backing. The gold-tone finish on the visible prongs shows minimal wear, retaining most of its luster. No maker's marks are visible from the front orientation, but the prong-set construction is a sign of better quality than glued-in counterparts.
