Australian opals sit wrapped in 22k gold and bridge the gap between a semi-circle of oxidized silver and 18k gold/silver bimetal. Wires radiate out from the lower edge of the opal and a gold dot accents the top. Below the earrings dangle a cluster of tanzanites. Earwires are 14k. Earrings measure 2 3/8 inches long and 1 1/2 inches wide.
