Why Does Silver Change Colour?

Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed. Silver oxidizes faster in places with a lot of light and high humidity.

Does real silver change color?

When the coating of silver flakes or scrapes off, the base metal underneath is revealed. All silver-plated jewelry will tarnish at some point, as the chemicals from daily wear and the exposed layer of silver react with air to change the color of a piece.

How do you keep silver from changing color?

To slow down tarnishing, clean your silver jewelry after wearing it. Oils from your skin accumulate on the surface of silver and can predispose it to oxidization. Use warm water to wash your jewelry items gently, and dry them with a soft cloth. You can also delay tarnishing by regularly polishing your silver jewelry.
