The Skyway has been particularly effective on Tanzanite. Using the Skyway lap, you can polish a wider variety of stones than the Creamway or the Greenway. At moderate lap speeds, you can polish on this lap with just a water drip on the surface due its refractory alloy/polymer composite surface. The baseplate is machined from aluminum alloy. Works well on gemstones between 6 and 8 Mohs hardness, such as Peridot, Tanzanite, Emerald, Aquamarine, Golden Beryl, and Feldspar. Skyway is perhaps the most versatile composite lap in existence. |
