An oval Coober Pedy opal is the focal of these earrings--each is wrapped in 22k gold and bridges the gap between two semicircles. One semi-circle is oxidized silver and the other is 18k/silver bimetal. Black spinel and 14k gold beads are clustered at the top, and below are pink sapphires and delicate silver chains. Earwires are 14k. These earrings measure 2 inches in length, and the discs are 1 inch in diameter.
