What is sterling silver? Sterling silver is an alloy of silver containing 92.5% pure silver and 7.5% of other metals, usually copper. Silver jewelry marked with a 925 is sterling silver jewelry that has been certified to contain 92.5% silver content. Sterling silver is harder than silver and is more suitable for jewelry making. Tips for making your Jewelry last longer - Remove your jewelry before you swim in chlorine or salt water. - Remove your jewelry before participating in activities that will cause you to sweat a lot. - Wait to put on your jewelry until after you have applied lotion, makeup or perfume. - Remove jewelry if you will be bringing it into contact with something hard. (For example, take off your ring before lifting weights.) - Store your plated jewelry where it won’t rub against other hard substances (a soft bag—one per piece of jewelry—is ideal).
