Copper is an amazingly soft and malleable metal that has been used for making jewelry since at least 8700BC. Copper boasts such a unique color, even after it oxidizes when it turns a blue-green color it maintains a unique beauty that cannot be replicated. Polishing copper jewelry will leave your copper jewelry gleaming as though it were new with minimal time and surprisingly little effort.
