To determine if a gold chain necklace is real, look for a hallmark or stamp indicating its karat value, such as "10K," "14K," or "18K," which suggests genuine gold. Additionally, you can perform a simple magnet test, as real gold is non-magnetic, or consult a professional jeweler for an acid test or electronic testing for more accurate results.
