To determine if a gold necklace is real, you can check for a hallmark or stamp indicating the karat purity, such as "10K," "14K," or "18K." Additionally, you can conduct a simple test at home using a magnet, as real gold is not magnetic, or consult a professional jeweler for an acid test or electronic testing for more accurate results.
