To determine if a gold chain necklace is real gold, you can perform a few simple tests. Check for a hallmark or stamp indicating the karat purity, such as "10K," "14K," or "18K." Additionally, you can conduct a magnet test, as real gold is not magnetic, or use a nitric acid test, where real gold will not react or change color.
