Vintage Rhinestone Infinity Loop Brooch

This item is a costume jewelry brooch featuring a stylized infinity or double-loop figure-eight design. The piece is constructed from a silvery-toned base metal, likely a zinc alloy or rhodium-plated brass. The outer perimeter of the two loops is pavé-set with eighteen round, brilliant-cut clear rhinestones which appear to be glass or crystal. These stones are held in place by small decorative prongs. The center of the brooch features a unique crossing element: a smooth, polished silver-tone 'S' curve that overlays two textured, wing-like or leaf-like shapes with fine linear striations. Chronologically, this style is consistent with mid-to-late 20th-century costume jewelry, approximately 1960s-1980s. The construction shows modular assembly common in mass-produced fashion accessories. Regarding condition, the stones retain moderate luster, though some appear slightly dull, suggesting minor surface oils or adhesive aging. The metal finish shows light surface scratches consistent with use. No hallmark or maker's mark is visible from the front view, suggesting a generic or department store brand origin. The craftsmanship is of standard commercial quality, focusing on visual sparkle and symmetry.
