Blue Czech Glass Turbine Bead Rosy Copper Earrings

Photos do not do these lovely beads justice. In dim light, they appear blue with reddish patina in the grooves. In sunlight, the beads appear not only cobalt blue and purple but have an almost rainbow prismatic effect. The beads are wire wrapped onto my handmade rosy copper headpins and are finished with my handmade rosy copper ear wires.
Approximately 1 3/8" or 35mm long
