Vintage Black Rhinestone Cluster Clip-On Earrings

This pair of vintage costume jewelry clip-on earrings features an elegant cascading cluster design. Each earring is constructed with a single clear, round brilliant-cut rhinestone at the top apex, followed by multiple elongated, marquise-cut black stones arranged in a stylized leaf or feather formation. The stones are prong-set in a silver-tone base metal, which appears to have a dark rhodium or gunmetal finish that complements the black stones. The earrings utilize a clip-on mechanism, typical of mid-20th-century fashion ranging from the 1950s to the 1960s. The black stones exhibit a high-gloss finish, while the clear top stones provide a sharp focal point. Regarding condition, there is visible surface wear to the metal settings, particularly on the prongs, and some dulling or 'yellowing' of the clear stones which may indicate age-related oxidation of the foil backing. A small amount of verdigris or buildup is visible between the settings. The craftsmanship suggests a mass-market but quality-focused mid-century manufacturer, though no specific maker's mark is visible from the top view. These are approximately 1.25 inches in length.
