Vintage Faux Pearl Screw-Back Clip-On Earring

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.
