Will the Stainless Steel Ring turn my finger green with long wear?
If a person has a natural high acidity level in his/her skin, it is possible for his/her finger to “turn green” from silver or gold jewelry, especially when the weather is hot and humid. Please don’t blame silver or a manufacture of silver jewelry. The green is actually caused by oxidation, and all silver will oxidize (it’s also what gives silver a tarnished look). There are some cheap jewelry items that cause the same effect. Most of them contain nickel. It’s not poisonous in small quantities but it can provoke a reaction in people allergic to nickel.
