Origin & Maker
Likely United States or European workshop, unbranded generic fine jewelry finding
Era & Period
Mid-20th Century / Retro period, consistent with the popularity of secure screw-back earrings from the 1940s to 1960s
Age Estimate
Circa 1940s-1970s production based on the mechanical screw-back style commonly used before modern friction posts took over
