Experts say that there are several metals that oxidize with your skin to give you a noticeable green ring around your finger. A ring made of copper is a common culprit; even silver and gold metals can cause discoloration.
Stainless steel, platinum and rhodium-plated jewelry, which includes almost all white gold, are less likely to react to your skin. Look for these specific metals when shopping for rings and decrease the chances of buying jewelry that will turn your finger green.
Keep soaps and lotions away from your ring finger if you want to prevent the green-finger effect. Something as simple as removing rings before washing your hands or before taking a shower can help. Avoid wearing rings in the pool as well. The chlorine from the swimming pool will damage your jewelry and leave the annoying stain.
Don't blame the jeweler and demand a refund as well as sending nasty emails when you get the green effect. Simply use a polishing cloth, clean the inside shaft and put on clear nail varnish which stops the green effect. Excitement also reacts with copper as your body releases more acid. Use of medication also produces the green effect.

Try clear nail polish as a quick fix. Apply a polymer coating to your ring and let dry. This creates a barrier between your skin and the metal, so that the ring can’t turn your finger green. Just remember to reapply the coating often because it tends to wear off.
