why does my copper wedding band leave a black mark on my finger?

Answer 1

You sweat, right?

Sweat provides a good way for copper to oxidize; it's kind of like how water can cause iron to rust. Oxidization is a chemical reaction wherein a chemical is combined with oxygen. It happens when you burn things, and it happens when metal rusts...amongst other things.

This can be easily fixed. Just coat the inside of the ring with transparent nailpolish...that should stop that black stuff from forming, since it will prevent the metal in the ring from coming in contact with your skin.

Answer 2

The copper is oxidizing and the residue is rubbing off on your skin.

Why the heck do you have a copper wedding band? It'll disintegrate within about 5 years.

Answer 3

If you look closely it would be green not black. Its because of oxidation. Either you get wet too much or you sweat too much. Usually after marriage we put on weigth so the ring becomes tighther and causes the moisture to get trapped between the skin and the ring. make sure you wash it during bath time everyday.

Answer 8

Get it plated with nickel or platinum - actually any platinum group metal such as Rhodium will do. You want an inert metal if it is next to your skin a long time. Cancer is nothing you want to mess with and chronic skin irritation is one of the ways you get skin cancer.

I favor Platinum or Rhodium.
