To determine if a gold necklace is real, look for a hallmark or stamp indicating its karat value, such as "10K," "14K," or "18K," which signifies its gold purity. Additionally, you can perform a magnet test, as real gold is not magnetic, or consult a professional jeweler for an acid test or electronic testing for more accurate verification.
