AI Appraisal Estimate

A single vintage screw-back earring featuring a small, cream-colored faux pearl. The pearl is set within a decorative gold-toned coronet or 'buttercup' style prong setting, which is integrated into a U-shaped metal frame. The mechanical fastening consists of a threaded screw post with a flat circular tension plate, a design characteristic of non-pierced jewelry popular from the late Victorian era through the mid-20th century. The metal displays a yellow-gold finish, though subtle tonal variations suggest it may be gold-plated or costume-grade base metal. A notable feature is a small integrated metal loop located just above the pearl setting, which may have originally supported a dangling element or 'drop,' which is now missing. The condition shows moderate wear and oxidation consistent with age, particularly notable as darkening on the screw threads and slight dulling of the pearl's luster. No visible maker's marks or metal fineness stamps are identifiable from this angle. Given the screw-back mechanism and overall construction, this piece likely dates to the 1940s or 1950s.

I have conducted a visual examination of this single vintage screw-back earring. The piece is a mid-century costume jewelry item, likely dating from the 1940s to early 1950s based on the screw-back mechanism. The construction utilizes a gold-toned base metal and a faux pearl in a buttercup setting. The condition is fair to poor; I noted significant oxidation on the screw threads and signs of wear on the pearl’s nacre. Crucially, the presence of an empty metal loop above the pearl indicates this is an incomplete 'orphan' piece, missing its original dangling drop. Furthermore, as an individual earring rather than a pair, its utility is restricted to replacement parts or repurposing. The market for mid-century costume jewelry is currently saturated, with high demand reserved for signed pieces (e.g., Trifari, Miriam Haskell) or sets in mint condition. Unsigned, single, and damaged base-metal earrings hold very little resale value. Comparable sales for similar individual vintage components typically fall under $15. This appraisal is limited by the digital nature of the inspection. Without a physical examination, I cannot test for metal fineness (such as a 10k or 14k gold content), though the visible wear suggests a plated base metal. To provide a definitive authentication, I would require an in-person acid test for gold content and a loupe examination to search for micro-stamps on the screw-head or frame. The absence of provenance or original packaging further confirms its status as a common vintage accessory rather than a high-value collectible.
