Thank you! The copper is covered with varnish, however I tried to wear bare copper jewelry too. After the piece was on me for the whole day - it still didn't paint the skin, I don't know whether it will if you wear it more than 1 day. But anyway those spots are easily washed off with water.
Thanks for the response, Dear! I see. I just asked because I'm not sure if those spots are healthy or not I've heard both positive and negative beliefs about copper, so I can't decide The varnish is a good thing. And without it, maybe the copper paints only if it is wet, or the wearer sweats. Have a nice day, and I wish you many good inspirations!
