Sterling Silver 925 is a metal alloy that contains 92.5% Silver 925 and 7.5% other metals to increase its strength. These trace metals help cause the sterling Silver 925 to tarnish due to various chemicals in the air. Some Sterling Silver 925 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 925 jewelry that is high polished, a liquid Silver 925 cleaner can also be used. Sterling Silver 925 jewelry should be stored in a plastic container/organizer or a small zip lock bag. Be sure jewelry is dry before storage. Thanks for Viewing
