So, how can you identify a jewel made up of pure gold? Other methods are possible.- Identify it by color: this consist of checking if there is a difference in color between the center of the ring and its edges, which are more exposed to friction. If so, it is possible that your ring is gold plated and not pure gold. - Identify it using a magnet: this is a fairly simple method. All you need to do is find a pretty powerful magnet like those used for purse closures. Gold being a metal that does not react to magnetic fields, if your jewelry is attracted to the magnet, then it is not gold.- Identify it using ceramics: this is a method to apply with caution. Rub your jewel against a bathroom tile or unglazed ceramic plate (do not use valuable items that could get bad). If it leaves a golden trail, it is a jewel in gold, if the trail is black it is a fake.- Have the jewelry authenticated. Finally, you can seek the expertise of a jeweler who will undoubtedly identify the precious metal without doubt.
