It can be used to remove minute scratches on stones such as opal, emerald, ruby, sapphire (including watch crystal), turquoise, dichroic glass, etc. It will give you the absolute best wet-polished look on semi & precious stones, decorative glass and similar. We recommend using this grade as a final polish with a Cushion Pad mounted on a Backpad.
