Late 60s/ Early 70s Enamel Flower Dangle Earrings

These enamel flower dangle earrings are very unusual. The earrings begin with a chocolate dome, followed by a small, gold-tone tube bead that holds 2 enamel flowers that hang back to back. One flower has yellow petals tipped in brown and a brown dimpled center. The second flower has plain yellow petals and the same dimpled center.  Both flowers are white on the reverse sides. The white side shows through making a base row of white petals. The clip on earrings measure approximately 3½”. The hinged back earrings are unsigned and are in excellent vintage condition.
