Rainbow Cal Silica from Mexico This is some material that I found at one of my suppliers. I have never seen it before I think he is the only one that has it. It is a really sharp looking stone. It has many layers of different colors. It is from Mexico and has been verified as a natural stone not man made. The certificate says it is composed of Calcite-Allophane. It has been treated the same as Turquoise. This makes it very stable. Be the first on your block to have a cab of this unique stone.
