That indicates the purity of the metal. Coins and gold bars are usually 999,9 out of 1000. In this case, the item contains 325 out of 1000 parts of pure (gold). In jewelry, the rest is usually filled with fine gold and gold mixed with other fine metals. Sterling silver has a purity of 975 out of 1000.
