Vintage Rhinestone Cluster Clip-on Earrings

This is a pair of vintage clip-on costume earrings featuring a dense, high-domed cluster design. The construction consists of multiple clear glass or crystal rhinestones in various shapes, primarily round and marquise-cut, set into a silver-toned base metal frame. The arrangement creates a textured, floral or starburst-inspired silhouette that captures light from multiple angles. The earrings utilize a mechanical clip-on backing, which was common in mid-century jewelry manufacturing (circa 1950s-1970s). The metal shows some slight tarnishing or oxidized patina consistent with age, while the stones appear to be prong-set for security. No obvious maker's mark is visible from this angle, but the craftsmanship suggests a mid-tier commercial production. The stones appear relatively clear, though some minor yellowing or 'dead' spots in the foil backing might be present upon closer inspection, which is typical for vintage costume pieces of this era. Overall, they represent a classic example of mid-20th-century formal costume accessories.
