Does 625 sterling silver turn you green?

Yes, 625 sterling silver can potentially cause skin discoloration, including turning skin green, due to its copper content. Sterling silver is typically made of 92.5% silver and 7.5% other metals, often copper, which can react with sweat, moisture, and certain skin types. This reaction creates a greenish stain on the skin, though it is not harmful. To minimize this effect, it's advisable to keep the jewelry dry and clean.
