Do titanium rings make your finger turn green?

No, titanium rings do not make your finger turn green. Titanium is a highly corrosion-resistant metal and does not react with the skin or moisture to cause discoloration. The green discoloration on the finger from wearing a ring is typically caused by the reaction between copper or nickel in the ring and sweat on the skin. Titanium rings are naturally hypoallergenic and do not contain these metals, making them an ideal choice for people who are allergic to certain metals.
