Sterling silver is a bright and beautiful precious metal with a long life span. The more you love and wear your sterling silver the more bright and shiny it stays. Tarnish can occur when sterling silver comes in contact with the oxygen in the air. If you are not wearing your sterling silver pieces every day, it is best to store in a resealable plastic bag or airtight container. If you do see some tarnishing, you can polish it with a jewelry polishing cloth.
