You are getting sleepy...very sleepy...no way! These beauties are going to keep you awake with their dazzling design! The earrings are made from precious metal clay, which once fired, becomes fine silver (99.9% pure silver as opposed to sterling silver which is 92.5% silver). They measure 1 1/4" (1 3/4" total dangle with the ear wire) by 3/4" at the widest portion. The ear wires are sterling silver lever backs.
