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.
