• IMPORTANT: Sterling silver is an alloy containing metals that react with chemicals found in air and produce tarnish; high moisture levels, exposure to sunlight, and contaminants such as salt water increase this reaction. Take steps to protect sterling silver by keeping it in airtight packages, using tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and storing your  sterling silver in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution.
