Premium Quality Keychain Test Magnet for Gold & Silver Jewelry

Proudly made in the USA! Instructions: Jewelry: A strong magnet helps in evaluating and identifying fake jewelry, but it is not fool proof. 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 found in 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. Anything that passes a magnet test (no reaction from the magnet) can be scrutinized further using other methods, such as doing an acid test.The magnet insert is rated at 10 lbs (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface). These magnets have an excellent feel and are very sensitive. The brass casing protects the magnet from chipping and breaking. Comes with a split ring for easy carrying, and a protective vinyl cap. It measures 3.1" long with rings extended, 2.14" without rings. Head diameter .5", and stem diameter .225".
