YES! Sterling Silver CAN tarnish! It is a misconception that it does not. We recommend you clean your Sterling Silver jewelry each week with regular Sterling cleaner, sold at most department stores for around $3.00-5.00. Over time, Sterling will tarnish. To restore tarnished Sterling we recommend Tarni-Shield or Tarn X polish and cleaner, which will restore the Sterling and its' stones, back to their natural luster and sparkle.
