I believe these vintage rings are brass, but surprisingly, after wearing one for weeks without taking it off, it hasn't tarnished my skin. They were probably manufactured in the 1970's and they have been allowed to oxidize naturally to a darkened patina.

We have sizes 5, 6, and 7 in stock. Be sure to specify your ring size in the "message" section at checkout. If you don't know it, download this sizing guide: http://www.ericaweiner.com/sizer.pdf
