All of our wire jewelry requires .925 Sterling Silver* in order to maintain their unique form. Life is all about form and movement. When you wear these wire earrings or pendants, they will move as you move. When you move, you reflect light differently; these wires will do the same. Whether you are going to a nice dinner, or sitting down for a Television interview : ) these wires will catch the eyes of everybody around (See them on the good friend of Kro-Gu co-founder Mladen Maricic: Emily Bunning, in her Fox Interview ~ http://www.myfoxny.com/Clip/11117617/emily-bunning).
