These clip earrings are obviously from the 1930s. They are marked “Czechoslovakian” on the ear clip, on the body of the earring and the glass is marked “Czecho”. These unique earrings appear to be copper based with tiny aqua stones. The centerpiece is a skull with huge green glass eyes. The hanging glass piece has three etched symbols. These earrings measure 4” in length and 1/2” wide at widest point.
