These solid Australian crystal opals flash green and blue and are set in 22k gold at the center of an oxidized silver flower. Below each opal is a cluster of London Blue Topaz on 14k pins. Earwires are 14k. These measure 1 1/8 inches from the top of the earwire to the bottom petal and just under 3/4 of an inch at the widest point of the flower.
