Copper and Mother of Pearl.

Earwire is Hypoallergenic niobium. Body is copper. It took us a long time to start making earrings; they get in the way of a bicycle helmet, so we never wear them, and forget they exist. But we also know that many folks love earrings, so here they are, just for you! See, we do listen, after all.
