Lovely crystal opals from australia are wrapped in 22k gold bezels. The gold contrasts perfectly with the oxidized silver beneath. Two tanzanites sit below the opals and a cluster of tanzanite beads in between. Earwires are 14k. These measure 1 1/8 inches from the top of the earwire to the bottom of the tanzanite and 5/8 of an inch across at widest point.
