When metals come in contact with acids in your skin (through sweat for example) it causes a reaction called oxidation. As the metal oxidizes, discoloration occurs. Please note that each person's body acidity is unique. People with a higher PH-balance may experience less oxidation. Likewise, people with higher acidity experience more oxidation and deeper discoloration. Chemicals. Soaps, lotions, cleaning solutions and other chemicals can react with the metal in your jewelry. The result is darkening and a green color. Be sure to remove jewelry before using lotions, perfumes or other bath and beauty products and also before cleaning the house. A copper base. Some metal jewelry is silver- or gold-plated and has a copper base. Copper is a great metal for making jewelry. Still, it will turn your skin after a while, especially if you apply lotions, use cleaning chemicals, or work up a sweat in the jewelry. Saltwater and chlorine. If you are a swimmer, beware of saltwater and chlorine. They will cause your metals to turn. Remove jewelry before taking your next swim. Improper storage. Failure to store jewelry in pouches or a jewelry box can result to tarnishing. Make sure you put your jewelry away. Storing it properly will preserve your jewelry and prevent green ring finger. Even sterling silver will tarnish and turn if it is not stored properly or is exposed to chemicals. Make sure you do all you can to protect your investment.
