Pure Copper Therapy Ring Band for Men & Women, Uncoated Solid Copper, Naturally Support Immune System; Trace Mineral, Natural Relief of Arthritis, Joint Pain, Carpal Tunnel; Size 5-12

Love it! Real copper and yes, it turns my finger green when it needs a little polishing (but it washes off). Saw a reviewer for a copper product rate it low because they thought it was not real copper. That's what copper does when you wear it on your skin and sweat on it. I wear it all the time in place of or with my wedding band. It looks great and helps my sore joints when I crochet too much.

Excellent ring, not too light and not too heavy. Slender smooth fit and beautiful cooper color.
