These magnets are an excellent aid for detecting fallacious materials when precious metal testing. Additionally they are ideal for preliminary tests before the filing and acid testing processes.

Furthermore, owing to metallic inclusions, synthetic diamonds may be attracted or repelled by this magnet as natural diamonds are not magnetic.

Please do not include magnets in your order if you have also ordered the following items as magnets have an adverse effect on them and will cause damage:

  • Movements
  • Circuits
  • Electrical equipment
  • Batteries
