  • Jewellery cleaning wipe
    Patent number: 9609992
    Abstract: It is surprisingly found that when diamond particles are embedded into an alcohol wipe, the cleansing wipe that is formed is extremely useful at cleaning diamond jewellery in the home. It is also surprising that, given the abrasive nature of diamond, the diamond particles result in a satisfactory clean without causing any damage to the surface of the diamond being cleaned. The final result is that the cleaned diamond has recovered most of its original fire, life and brilliance.
