These are very vintage Chinese butterfly earrings. They are solid silver with beautiful enamel. The butterflies are enameled purple with red and blue trim. They are enameled on both sides. The earrings measure 7/8" wide and just over 1/2" long for the butterfly only. Each of the ear wires are marked silver where the wire connects to the wing. Very nice condition for their age. c1970. They are bright and beautiful and unique.
