If you throw out that piece of jewelry because it discolors your skin and you think it's cheap, you may be throwing away something of actual value. There are many different reasons a piece of jewelry -- even a relatively expensive one -- could cause your skin to turn a different color. Finding out the reason behind the discoloration can save you the heartache -- and expense -- of having to throw it out.
Copper and Oxidation
Many less-expensive pieces of jewelry do contain higher concentrations of copper, one of the cheaper types of metal. When the copper rubs off on your skin and is then exposed to sweat from your skin and oxygen in the air, it begins to oxidize, much like a penny or the Statue of Liberty, turning a light green color.
Allergic Contact Dermatitis
Copper isn't the only metal that will discolor your skin, however. Many people have allergic reactions to certain types of metals, resulting in a condition known as allergic contact dermatitis. This condition can cause a rash on your skin at the spot of exposure, turning your skin red and splotchy. For example, nickel is a common metal used in jewelry and can cause rashes and other skin discoloration in people who are allergic to it. Getting your ears pierced with a nickel-plated device may also cause allergic contact dermatitis.
Other Factors
Besides cheap metal and allergies, some properties you come in contact with on a daily basis may be playing a role in your skin discoloration at and around where you wear your jewelry. For example, corrosion of elements like silver or copper can form black marks and smudges around your jewelry, especially as they wear out or are exposed to harsh chemicals.
Prevention/Solution
The easiest way to avoid many types of skin discolorations caused by your jewelry is to be informed about what's causing it. For example, if you know you're allergic to nickel, paying close attention when you shop for jewelry can help eliminate the problem. If corrosion seems to be the issue, take your jewelry off when you wash your hands, shower or handle caustic chemicals to avoid ill effects. In most cases, simply wiping off your jewelry and washing your hands will make the discoloration go away.
Warning
Allergic contact dermatitis can be a serious condition if the exposure is for a long enough period of time and the allergy is severe. Complications may include a darkening or blackening of the skin or the appearances of blisters or boils, which may pop and crack, causing pain. Consult your doctor if you think you have a skin condition that requires medical attention, and avoid wearing jewelry until you can determine the cause.
