Sterling Silver is a metal alloy that contains 92.5% silver and 7.5% other metals to increase its strength. These trace metals help cause the sterling silver will tarnish due to various chemicals in the air. Some Sterling Silver jewelry is intentionally blackened to bring out details or to give an antique look. A jewelry polishing cloth will remove the tarnish while leaving the blackened areas. For Sterling Silver jewelry that is high polished, a liquid silver cleaner can also be used. Sterling Silver jewelry should be stored in a plastic containerorganizer or a small zip lock bag. Be sure jewelry is dry before storage. Thanks for Viewing To combine shipping: Enter items in ADD TO CART, then proceed to check out.
