||Why does silver discolor fingers?|
Some customers may think that faulty manufacturing or underkarating might be the problem when a ring 'turns,' blackening or discoloring the skin and clothing, or the jewelry itself. The most common reason is metallic abrasion, caused by makeup on skin or clothing. Cosmetics often contain compounds harder than the jewelry itself, which wear or rub off very tiny particles. Very finely divided metal always appears black rather than metallic, so it looks like a jet-black dust. When this dust comes into contact with absorbent surfaces such as skin or clothing, it sticks, forming a black smudge. To prevent this, try switching cosmetics. If this is not possible, remove rings and other jewelry while applying them, and clean skin areas in contact with jewelry with soap and water.
Another cause is actual corrosion of the metals. - forming very dark chemical compounds - under moist or wet conditions. When a person perspires, fats and fatty acids released can cause corrosion of silver, when exposed to warmth and air. This problem can be worse in seacoast semitropical areas, where chlorides combine with perspiration to form a corrosive element that discolors the skin. Smog fumes gradually attack silver and are evident as a tarnish that rubs off on the skin. Remove jewelry often and use an absorbent powder, free of abrasives, on skin that comes into contact with jewelry. Remove all rings before using soaps, cleaning compounds or detergents and clean your rings frequently. As well as solving the problem, you'll be amazed at how much better the rings look. Most of our silver rings at irecrafts, are coated in a special anti-tarnish coating. So they will never tarnish!
