Aurora Borealis Accents Appraisal

Rhinestone Circular Brooch with Aurora Borealis Accents

This item is a circular rhinestone brooch, approximately 1.5 to 2 inches in diameter, constructed from a silver-tone metal base. The brooch features a continuous ring of various-sized rhinestones, most of which appear to be clear or colorless, cut in a faceted style to maximize sparkle. Interspersed among the clear stones are several rhinestones with an 'Aurora Borealis' (AB) coating, which gives them a distinctive iridescent shimmer, reflecting a spectrum of colors including purples, oranges, and blues depending on the light and viewing angle. The setting appears to be prong-set or cup-set, holding each stone securely. The overall shape is a classic wreath or open circle design. On the reverse side, a simple straight pin with a C-clasp or rollover safety clasp mechanism is visible, indicative of typical mid-20th century construction for costume jewelry. The metal base, while largely obscured by the stones and their settings, does not show obvious signs of tarnish or significant wear from the visible portions, suggesting a decent quality base metal, possibly rhodium-plated for durability and shine. The condition appears good overall, with no visibly missing stones or major damage. The consistent sparkle and variety in stone type point to a deliberate design choice, likely from the mid-century (1940s-1960s) where such rhinestone pieces were highly popular. The craftsmanship seems solid for costume jewelry, with stones evenly spaced and securely set. There are no discernible maker's marks or signatures visible in the provided image.
