Test with a magnet
Check whether the object is magnetic. Gold is not magnetic, so if the object is attracted to the magnet, it is not gold. But just because the object is not magnetic does not mean it is gold.
Check the hardness
Test the material's hardness with a steel file. Gold is soft, and bends easily, so if the material bounces back from the file; it is made of some other material.
Test with acid
Put on your gloves and glasses and apply a drop of nitric acid to the file scratch. Then, rinse with running water. If there is no reaction in the metal, the material is gold; if the object turns green, the object is made of a base metal; and if it turns milky, the object is gold-plated silver.
Take the object to a jewelry shop
If all else fails, take the object to a jewelry shop and have it x-rayed.
