A green thumb is a good thing. A green neck, wrist, or ring finger...not so good! If you've ever had a piece of jewelry that makes your skin yellow or green you've most likely asked yourself what causes it. Usually, it's a reaction to base metal to anyone who buys and wears low cost jewelry - it can happen with necklaces, brooches, bracelets - I've even seen it happen with engagement rings. Skin greening can happen to some people more quickly than others~ though, because everyone's skin is different.
Even the more expensive jewelry can turn people's skin green~ reason being it's not totally pure~ no matter how much gold or silver is in it. Platinum is one metal that usually doesn't react with skin so no worries if you buy platinum jewelry. If you have gold jewelry and want to stop it from turning your skin green be sure its not gold plated or gold rinsed jewelry – its a cheaper metal with a thin gold layer that can rub off. If you have solid gold jewelry switching to eighteen karat options will lower your chances of green skin. Copper will react with skin and there isn't a whole lot you can do about that.
Avoid sweating in your jewelry because that can speed up the reaction between your skin and the metal you can also get a special coating put on – in order to try to stop the reaction or minimize it. If you do this you can wear inexpensive jewelry whenever you want. Remember- your skin turning green is a harmless reaction. It's a chemical skin reaction and not allergies. Allergies will causes reddening and also will make your skin inflamed and itchy. Which is a far cry from green skin. If you do show signs of allery stop wearing the jewelry. Green skin shouldnt scare you ore keep you from wearing your favorite pieces you'll just have to keep the area clean so it doesn't look bad.
At the end of the day coating your jewelry is generally your best choice.
