To determine if a gold necklace is real, you can check for a hallmark or stamp indicating the karat weight (such as 10K, 14K, 18K), which signifies its authenticity. Additionally, you can conduct a simple magnet test, as real gold is not magnetic, or consult a professional jeweler for an acid test or electronic testing for a more accurate assessment.
