To determine if a gold chain necklace is real, check for a hallmark or stamp indicating the karat value (such as 10K, 14K, 18K), which signifies authenticity. You can also perform a magnet test, as real gold is not magnetic, or consult a professional jeweler for an acid test or electronic gold tester for a more accurate assessment.
