AI Appraisal Estimate

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.

I have conducted a visual inspection of this pair of vintage clip-on earrings. The design is characteristic of mid-century costume jewelry, likely dating from the 1950s or 1960s. The aesthetics, utilizing a combination of clear chatons and black marquise-cut glass stones in a 'leaf and berry' cluster, are typical of unsigned mass-market pieces produced by manufacturers like Coro or Trifari, although the absence of a visible hallmark suggests a tiered-production brand. The condition assessment reveals significant age-related wear. The clear stones exhibit 'fogging' or yellowing, indicating oxidation of the foil backing, and the metal prongs show visible plating loss. The presence of verdigris (green oxidation) in the recesses further suggests long-term exposure to moisture. The current market for unsigned costume jewelry of this era is saturated, with demand focused primarily on pieces in 'new-old stock' condition or those by high-end designers like Schiaparelli. The lack of a maker's mark and the visible deterioration of the foil backings significantly cap the value. For a definitive authentication, I would need to examine the clip mechanism for hidden marks, conduct a lead/pot metal test on the base, and inspect the stones under 10x magnification to confirm they are glass rather than acrylic. This valuation is based solely on the provided visual information and prevailing secondary market trends for vintage accessories in 'fair' to 'good' condition.
