Vintage Citrine and Aurora Borealis Rhinestone Brooch

This is a mid-20th-century costume jewelry brooch featuring a tiered geometric or floral-inspired design. The piece is constructed from gold-tone base metal with a variety of prong-set glass rhinestones. It features four large oval-cut stones in a deep amber or root beer hue situated at the corners, interspersed with marquise-cut stones of a lighter citrine shade. The center is dominated by a round Aurora Borealis (AB) rhinestone, which displays an iridescent shimmer, flanked by smaller AB accent stones. The construction utilizes high-dominance dog-tooth or 'fleur-de-lis' style prongs, typical of 1950s or 1960s craftsmanship. The overall arrangement is symmetrical and layered, creating a three-dimensional effect. While no maker's mark is visible from the top view, the style is consistent with mid-century manufacturers like Sarah Coventry or Weiss. The condition of the stones appears good with no immediate visible chips, though the metal settings show a slight aged patina and minor surface wear consistent with a vintage piece of this age.
