I'm sure you have had it happen to you at some time in your life. You buy a ring, a necklace, a bracelet simply because you like it. The next day you look down and you have a green ring where the jewelry is. Why does this happen? What causes your skin to turn green when you wear certain jewelry but not others?
Acidity in Your Skin
Metals in the ring or other jewelry can react with the acidity in your skin. The higher the acidity level, the quicker this reaction may happen. Heat and humidity or sweating also increase the reaction. According to Discovery.com, the acids in your skin cause copper in the jewelry to begin to corrode, forming a salt compound. These salts are green and when they are absorbed in the skin, your skin turns green.
Is it an Allergy?
Allergic reactions to metal include redness, swelling and itching. If you are not experiencing any of these but simply have a green area where the jewelry touches your skin, it is not an allergic reaction.
Avoiding a Green Reaction
Understand How Jewelry is Made
One way to avoid having green fingers is to understand how jewelry is made. Gold jewelry is stamped with 10K, 14K, 18K or 24K. The higher the number, the larger amount of pure gold in the jewelry. However, pure gold is soft so usually other metals, such as copper, tin or nickel, are added to make it stronger and more durable. It is these metals which react with the acidity in your skin. When buying gold jewelry, you can make sure it is real gold by looking for the stamp. Less expensive jewelry may be made with cheaper metals and then coated with gold.
Silver jewelry can also cause your skin to turn green or the jewelry could be made of cheaper metals and coated with silver.
Sweating speeds up the reaction. Avoid wearing jewelry that may turn your skin green on hot days or on days you may sweat.
Coating Your Jewelry
Many times, quality silver or white gold jewelry is coated with rhodium, which prevents this reaction. You can talk with the jewelry store to find out if they provide coating for other jewelry that you want to wear but are concerned about unsightly green spots on your fingers, arms or neck. This coating will give your jewelry a bright sheen.
_Clean Your Jewelry Often _
You can keep silver jewelry clean by using a polishing cloth once per week. Doing this should help stop any reactions from occurring.
Use Stainless Steel Jewelry
If you consistently have a reaction to jewelry because of high acidic levels in your skin, you may want to consider wearing stainless steel jewelry. Stainless steel is untarnishable, strong and should not react with your skin.
