Sterling Silver Tarnish:

Over time, any sterling silver jewelry piece exposed to air will tarnish. … It’s the other metals, primarily copper, that cause sterling silver to tarnish. The copper reacts to moisture and sulfur in the air, causing the tarnishing reaction. Silver tarnishes faster in areas with high humidity and air pollution.

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.
