To determine if a gold necklace is real, you can start by checking for a hallmark or stamp indicating its karat value, such as "14K" or "18K." You can also conduct a magnet test, as real gold is not magnetic, or perform a simple acid test using a gold testing kit to observe any color change, which can indicate the presence of other metals.
