Vintage Iridescent Domed Screw Back Earrings, Round Soap Bubble Lucite Cabochon

Terrific vintage iridescent domed screw back earrings. Likely dating to the 1960s or so, I believe the cabochons are made of lucite or similar. They have a unique soap bubble sheen to them. CONDITION: GOOD (Poor-->Fair-->Good-->Very Good-->Excellent-->Mint): Some wear to the metal backings, a few scuffs on the cabochons. MARKINGS: None MEASUREMENTS: 0.75" in diameter WEIGHT (w/o packaging): 0.2
