The natural dye of the Statue of Liberty is made of copper, which turns blue-green when it is oxidized. Oxidation usually involves the reaction of some elements with oxygen, and it can also describe other chemical reactions that lose electrons. In the case of the Statue of Liberty, color conversion includes a series of these reactions.
A similar process can cause jewelry to discolor your skin. Refinery29 explained that the trinkets in question may contain copper or other metals, which will produce new colors after oxidation. Even gold and sterling silver objects will change color because they are rarely made of pure gold or sterling silver.
The catalyst for the reaction can be anything on your skin, from soap or lotion to ordinary old sweat. "One day, it may not affect me," Susanna Friedler, a certified researcher on the board of the American Academy of Dermatology, told Review. "Maybe another day, it depends on the heat and sweat of my skin and how close it is to my skin."
How to stop the ring from turning the finger green?
If you want to avoid this problem completely, please insist on wearing materials that will not change color, such as platinum and stainless steel. But before you throw away all your favorite bargaining rings, you should know that there is a very effective way to prevent green from staining your fingers: just apply transparent nail polish on the bottom. This technique should be applied to any jewelry, although complex bracelets and necklaces may be more difficult to draw. )
