Vintage Gold-Tone and Pink Enamel Screw-Back Earring

This item is a single vintage screw-back earring, likely dating from the mid-20th century (circa 1940s-1950s). The earring features a circular, slightly domed face with a central soft pink enamel or ceramic cabochon insert. This central element is surrounded by a textured gold-tone metal border, which exhibits a fine, milled or beaded edge detail that adds a touch of classic sophistication. The metal appears to be a base metal with gold plating, showing signs of aging and a duller patina consistent with its estimated age. The reverse side features a traditional screw-back mechanism, which was the standard before the widespread popularity of pierced earrings. This mechanism consists of a threaded post and a small knurled tightening knob, allowing the wearer to adjust the pressure on the earlobe. The condition appears fair to good; there are no visible chips in the pink central element, though the metalwork shows minor surface oxidation and wear to the plating, particularly around the edges and on the screw mechanism. No visible hallmarks or maker's marks are present in the image, suggesting it may be a mass-produced piece of costume jewelry from the era. The craftsmanship is typical of mid-century costume accessories, focusing on aesthetic appeal and durability for daily wear.

Based on my visual examination of this single vintage screw-back earring, I estimate its current fair market value between $5 and $15. This assessment is based on several key factors. Firstly, the item is an 'orphan' (a single earring), which significantly reduces its desirability and value compared to a complete pair. The piece is mid-20th-century costume jewelry, likely 1940s-1950s, constructed from base metal with a gold-tone plating and a pink enamel or glass cabochon. While the enamel remains intact, the metalwork shows notable oxidation and thinning of the plating, which is expected for mid-century costume pieces. Market demand for unmarked, mass-produced costume singletons is low, typically appealing only to collectors of specific eras for use as buttons, 'repurposed' jewelry components, or to someone seeking to match an existing orphan. To achieve the higher end of the estimate, the screw mechanism must be fully functional. Limitations: This appraisal is based solely on high-resolution imagery. Without a physical inspection, I cannot verify the base metal composition or confirm if the central insert is glass, ceramic, or a polymer. An in-person examination would be required to rule out the presence of precious metals (though unlikely given the wear patterns) and to search for micro-hallmarks that might elevate the manufacturer's pedigree. No provenance was provided; documentation regarding original packaging or retail history could slightly influence the historical context but would not significantly alter the valuation of a single, unsigned costume piece.
