What causes the green mark?
Copper reacts with moisture, salt and acids from your skin. The green residue is copper salt. Heat and humidity speed this up, which is why it happens a lot in Pakistan's summer.
Is it harmful?
For most people it is not harmful. It is a sign the metal is reacting, and it can come with itching in sensitive skin. If you get redness or a rash, stop wearing the piece.
