Comfortable single chain wraps around the ear invisibly. If you are looking for a multiple chain look, then we would suggest layering one chain in a lower hole, and a smaller chain in the piercing or piercings above it, for a tapered look. All colors of gold are nickel free and hypoallergenic. White gold is specially alloyed with palladium to maximize the hypoallergenic properties of that color. Item sold singly.
