Gem-Shine Polishing Wheels are unique polishing wheels designed for removing light surface scratches from soft stones such as onyx, cabochons and opals. The Gem-Shine wheels are different as these wheels are impregnated with a polishing paste to provide scratch removal and a final polish on the stone’s surface. Simply apply a little pressure to these wheels to allow the paste to flow out onto the stone and then return to a light polishing application with the same wheel. The results are amazing! Comes supplied in a box with (5) Gem-Shine Polishing Wheels and a reinforced 3/32” mandrel.
