The Last Lap disc is best suited for stones such as Chrysoberyl, Corundum, Spinel, Cubic Zirconia, YAG, GGG.
This lap needs to be charged and have an initial break in period to work properly. To charge the lap use the 50,000 diamond slurry that is provided with the lap and a piece of agate with a rounded edge.
We recommend storing all polishing laps in individual disc protectors to prevent contamination when not in use.
These are high quality products manufactured completely in the USA.
