It could be an ear/nose ring, but you don't see very many everyday body items made from copper because our body corrodes it easily and that turns the skin green (or worse if you are allergic to it.) My wife got a cheap pair of "silver" ear rings in Mexico a few years back and got a nasty infection/reaction after wearing them a few days, they were just silver plated copper.
There were some copper earspools and beads, but they appear to have been mostly burial/ceremonial items vs everyday use items.
I'd still go with a bent awl/needle or a copper hook.
