These disk dangle earrings were handmade in copper by your artist, Cornelia. Notice that one earring's shape is concave and the other is convex. The cosmic design earrings are naturally oxidized so that the patina creates richness and depth. The ear wires are made of surgical steel to minimize allergic reaction. The total length including the ear wire measures about 2 inches (50mm). Please feel free to contact me if you have questions.
