To identify a real gold necklace, look for a hallmark stamp indicating the karat value, such as "10K," "14K," or "18K," which signifies the gold's purity. Additionally, perform a magnet test; real gold is non-magnetic, so if the necklace is attracted to a magnet, it likely contains other metals. For further verification, consider consulting a professional jeweler for an acid test or electronic testing.
