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 your sterling findings by keeping them in airtight packages, use tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and store sterling findings in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution
Rhodium is a rare, naturally occurring member of the platinum group of metals – making it a deluxe metal. It’s extremely tough, able to resist corrosion and scratches. It is because of this toughness and highly reflective nature that rhodium makes an excellent plating material.
