||14,000 mesh, 100cts. per bottle. Normal curve diamond shows an even distribution of diamond particle sizes in the specified range. Users need to experiment and determine which micron sizes work best for them.
Normal curve 0-2 works well for sapphire, tourmaline, amethyst, and garnet. Short curve, with a higher percentage of small particles may be more suitable for emeralds. 0-1 would be too slow for hard stones so most of the polishers prefer 0-2 because it can remove small scratches and polish quickly. Manufacturers should experiment to see which sizes work best for their particular application.
