Rhodium is a rare, durable substance used to coat many different metals such as copper or sterling silver helping to prevent them from tarnishing. It is highly reflective and when applied to other metals used to make jewelry, is what gives it its shine. Love wish pearl pendant jewelry but prefer a longer chain?
