Jewelry: The magnet should always be the first test you perform on an unknown piece of jewelry. If there is any steel or iron present, the magnet will attract. These metals are common in costume jewelry where they are electroplated with gold or silver, but they will never be present in high quality jewelry (with the possible exception of clasps, which sometimes have steel springs inside them). It is important to note, however, that not all fake jewelry will have these metals present because there are other non-magnetic metals that can be used as a base. A deliberate forgery might have metals such as brass or tungsten as a base metal, and these are non-magnetic just like gold and silver. Anything that passes a magnet test (no reaction from the magnet) can be scrutinized further.
