The Moss Agate stones can been seen thru, as shown by the golden reflection at the bottom of the stones. That is the sterling silver backing that is visible thru the stones. The tanzanite dangles dress these earrings up a little. The earrings measure 1 3/4” long. All set in Sterling silver and hang from sterling silver ear wires. As a little surprise- the back the earrings are sterling silver that I have patterned with my rolling mill.
