After the sweat and the silver and copper in the gold jewelry are in contact with the copper, chemical reactions will produce silver chloride and copper sulfide, which will cause the jewelry to discolor or fade. 2. After the silver and copper in the gold jewelry are contacting, chemical reactions will occur, produce silver chloride and copper sulfide, and show dark black chemical salt. This kind of chemical salt is often dropped from gold jewelry to pollute the skin of the wearer, leaving a very obvious black stain on the skin.
