Neodymium ring, small and golden, suitable to design jewelry (although not to be called ‘nickel-free’ the nickel coat is covered by the golden one). All rings can be fastened by a nail or screw through their middle hole – but becareful: Do not spoil coating. Neodymium magnets must not be rasped or sawed – if their coating is not intact they will corrode. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets.
