Light & Comfortable, 1mm thick 14K Yellow Gold Fill twisted wire, formed into a small hoop, simply slide onto your upper ear at the top. Can also be slid onto the side of your nose as a faux hoop piercing. Squeeze gently to size. 1mm wire, available in 8mm or 10mm diameter, the 8mm is what I recommend if you wear your cuffs at the top of the ear, 10 mm works best across the middle.
