Although that green tinge is often associated with cheaper jewelry, it also happens with the pricey stuff too! While the green may seem alarming at first, it’s actually a fairly common chemical reaction. The green colour is usually a result of a metal in the jewelry reacting with your skin — or something on your skin most likely. Examples include lotion, soap, hair product, and even your own sweat and skin moisture!

The easiest way to prevent this green stain is to avoid the products that cause it. For example, taking your jewelry off before washing with soap or styling your hair with products will also reduce your chances of going green.
