Green Ring Woes
You put on your favorite piece of jewelry, let's say a ring. Maybe it's made of silver or just an attractive piece of costume jewelry. It could even be gold. When you twist it off that night you notice something odd. Your finger now spots a ring of green or black where the ring rested.
A common misconception is the discoloration is a sign of an allergic reaction. Allergies don't cause metal to turn your skin green or black. Metal allergies are actually rare, but the most common one is nickel and usually occurs with costume jewelry. An allergic reaction results in redness, sometimes swelling, and burning or itchiness where the jewelry was. You can allergic to a piece that causes skin discoloration, but the two phenomena aren't related.
Skin discoloration occurs when the acids in your skin react to the metal. It happens most often with jewelry containing copper, which includes some costume jewelry and some silver alloys. Some gold plated gold jewelry may contain copper or another metal that causes discoloration. Stainless steel and platinum jewelry are the safest bets if you want a ring that is guaranteed not to discolor skin.
You can prevent your favorite piece of discoloring jewelry from causing green rings, though, so don't toss them! The simplest fix on costume and silver jewelry I have found is to coat it in clear nail polish. The polish requires periodic replacement, but it does give the jewelry a nice shine. I wouldn't attempt this with expensive jewelry though!
