Gold Smudge

A gold smudge is a colored smudge, left by jewelry or other metallic object, on the skin of the wearer. Although precious metals are usually non-reactive, in rare cases they may react with the environment. Usually these special cases involve chemical reactions between the skin of the wearer and the metal,or the alloy, as is sometimes the case during pregnancy or with people who are allergic to that metal. Cosmetics, detergents, pollution and other such factors can also be culprits in causing "gold smudge".
