【Product Size】0.47 x 1.57 inches with N40 Neodymium Magnets; Package: 2 pack; Pull Power: Over 2 pounds per magnet, 8 pounds for the pair. This gold testing magnet is the perfect size and strength for identifying fake silver and gold jewelry!
【Jewelry & Coin Testing】Identify fake/plated jewelry, which often has steel or nickel alloys as the base material (some alloys, like nickel-silver and German silver are non-magnetic, despite having ferrous metals present). Generally, the magnet test is only the first test performed when verifying the authenticity of coins and jewelry, before density and acid testing.
【Precious Metals Testing】Identify/sort chrome plated items from polished aluminum, silver, and non-magnetic grades of stainless steel (chrome plating requires a nickel layer, which is magnetic). Identify and sort solid brass and bronze from steel-plated items (handy in the antique market and hardware store).
【Practical Magnetic Keychain】This magnetic keychain is strong, small, light in weight, and easy to carry. You can put it in your pocket or purse when you go out. It provides you with a versatile multi-functional magnetic testing tool.
