DID YOU KNOW? Research tells us that it was probably the Chinese who found a way to take the natural process of abrasion a step further, using water and sand. Their perfect spheres of rock crystal were made by chipping the quartz until ti formed a rough ball, then rolling the ball up and down a trough filled with water and sand until it was smooth. Progressively finer sand was used as the work advanced, sometimes over a period of years. The last polish would have been with finely ground garnet to eliminate scratches and provide a perfectly clear surface. Aren't you glad you can purchase rock tumbler polish and grit and accomplish this process in just a few weeks?!
