The best way to determine if your earring is gold or silver is by using a jeweler's loop. This tool can be used to test the purity of an object, such as an earring. If you have access to one, simply place the loop over the earring and pull it away from the surface. If the earring slides off easily, it is likely made of silver. However, if the earring remains in place, then it is likely made of gold.
