Answer
The only way to test is with a variety of acids that are available at jeweler's supply stores. For gold, there is a tool that is used in conjunction with acid called points. If you don't have someone to teach you how to test, it is best to take the piece to your local jeweler for testing. If they can't test, how do they stay in business?
