Sterling silver can be worn in water, the pool, the ocean, or wherever your adventures take you. Sterling silver can tarnish over time, but can easily be cleaned and restored. Tarnishing is a natural oxidisation process that does not damage the silver itself and is not permanent. Sterling silver tarnishes due to the added alloys for strength: typically copper or brass. Clean sterling silver with the included polishing cloth. Severe tarnishing can be remedied with vinegar and baking soda, but be careful it's not too harsh, especially for your stones.
