These earrings are a complex and beautiful variation of different design elements and materials. The green tube beads were handmade from copper tubing cut to length and oxidized with non-toxic household items. They mellowed into the wonderful green you see now. I paired them with genuine turquoise beads in the same color. The intricate design feature and the bicone beads at the bottom of the tube are pewter. The rings, pins, and earwires are sterling silver. The pictures do not do justice to the beautiful texture the oxidized beads have acquired.
