mid-century floral screw-back earrings (likely 1940s–1950s)

mid-century floral screw-back earrings (likely 1940s–1950s) made of a base metal like brass or gold-tone pot metal with faceted pink glass or rhinestone centers. • The metal shows significant patina and possible "greening" (verdigris), which is common in older costume jewelry. Stones are missing around both middle pink stones. But the middle pink stones are both in tact on both earrings. • Closure Type: Screw-backs were most popular from the 1920s through the early 1950s. After that, clip-ons became the standard until pierced ears regained popularity in the 70s. This "vintage" appeal is a selling point. • Material: These are likely costume jewelry.
