This unmarked beauty is new old stock, dating back to the early 1960-s, with the earrings still on card. The chains look like black glass, but are actually metal. The finish, which appears to be enamel like, is in excellent shape. It measures 24 inches, and the clasp has a coil;ed section of the chain attached. Clasp measures about 22mm n diameter, or about 7/8", and has a box type catch. The earrings are slightly smaller, about 19mm. A striking and unique set.
