Alpha Polisher Lap
The Alpha™ is for any gem materials that will polish with Aluminum Oxide. The Alpha lap works well on gemstones between 7 and 8 Mohs hardness, such as Beryls, Garnets, Tourmaline, and many others. Use the lap at low to moderate lap speeds, with just a water misting on the surface. You can also use the lap with Alumina slurry to speed up performance.
