Ideal for emeralds or any other stones that may be heat senstive. Effective for any kinds of gems except corundum. Works for stones in the 1-2 ct. size range.
The polishing powder is impregnated into the resin bond lap eliminating the need for any additional agents. All that is added is water. This long lasting lap with a polishing layer of 6mm, only requires dressing from time to time. Recommended operating speed is up to 1500 RPM.
Instructions and maintenance for the resin bond lap: To get the best results, it is recommend to first cut the stone on a cutting disc of 600 or 1200 mesh. Polishing is acomplished with a constant drip of water by moving the stone across all the area of the lap, to obtain a brilliant flat surface. It is important to move the stone across the entire surface of the lap in order to maintain a smooth and flat polishing surface.
When a light dressing is needed, a fine carborundum bar can be used to remove any ripples and to restore a perfect flat surface. Plenty of water is required while dressing. No scoring is needed!!
