How can you tell if something is sterling silver?

To tell if something is sterling silver, first search it for purity marks. Makers often indicate sterling silver with hallmarks like “925,” "STER" or "STERLING," but some pieces may feature alternate hallmarks. Researching the markings on your piece using trusted online resources can help you identify its materials. When in doubt, seek the opinion of a certified appraiser or other knowledgeable expert.
