How to Tell if My Jewelry is Silver

Most silver jewelry is sterling silver and should be stamped with a hallmark of either “.925” or “sterling.” Sterling is 92.5% silver. The other 7.5% metal generally is copper.

If your jewelry is stamped “German Silver”, “E.P.N.S.(Electro Plated Nickel Silver), “Alpaca”, or “Nickel Silver” you don’t have sterling silver but rather you have an alloy of Nickel and copper with no silver. Unfortunately we don’t buy these items. If you can’t find the hallmarks on your jewelry, don’t worry. Bring it in and we will gladly test it for you at no cost.
