Silica from Mexico This material is a new discovery from Mexico and has many layers of different colors: red, brown, green, tan, blue, yellow, white and others. It has been verified as a natural stone not man made. It is composed of Calcite-Allophane (Blue and green) and silica with various trace metals that cause the other colors. It has been stabilized the same as Turquoise. This makes it very stable and easy to cut and polish. Be the first on your block to have some of this unique stone. There is a big controversy of whether this stone is natural or man made. Here is what I know as of 4/2/2003: CLICK HERE FOR INFO |
