Sterling silver is an alloy made of 92.5% pure Silver and 7.5% Copper
Excessive sunlight, oxygen, and moisture in the air will tarnish sterling silver jewelry, so be sure to properly store your jewels when you’re not wearing them.
Just be sure to minimize your jewelry’s exposure to the chemicals in sweat, personal care products, and pools and hot tubs.
Keep your jewelry away from the sun and in a cool, dry place.
The best way to store your sterling silver pieces is in a small Ziploc bag. Place your sterling silver jewelry in a small Ziploc and seal all the air out. Alternatively, you can also purchase anti-tarnish bags to store your jewelry in.
Clean your sterling silver jewelry with warm soapy water. When it comes time to clean your sterling silver, mix warm water with a mild soap in a bowl, and let your jewelry soak for a few minutes. Dry it with a soft, lint-free cloth.
