Andamooka is a small mining town in the desert of South Australia and is the only area that produces Rainbow Opal Matrix. This type of opal is found in minuscule pores interspersed throughout its limestone host rather than in seams such as found in Coober Pedy. The limestone is white and chalky and because it does not refract light the color of the opal appears to be faint and barely discernible.

To bring out the play of colors the opal has to be treated. Treatment consists of cooking the stone in sugar and then carbonizing the sugar which turns the sugar black. This turns the base rock black and highlights the opal found in the stone. It does not increase the color, just enhances the ability to readily see whatever color is there. A great advantage of this material is that it is very stable, will not craze and the colors of each piece will amaze you.

Rainbow Opal Matrix is coarse grained and it is difficult to obtain a high end polish obtainable on other opal types so it is typically finished by the application of a clear coat product. This coating does not increase the color of the opal and is only the equivalent of a final polish to highlight the magnificent combination of colors in this opal.

Rainbow Opal Matrix releases inhibitions, helps to release anger, brings comfort during fear or grief, strengthens memory and encourages freedom and independence. It also increases creativity and original thoughts and aids in stimulating intuition and insight. Rainbow Matrix Opal helps you work towards fulfilling  your deepest desires, dreams and ambitions and to work with your spiritual and animal guides.
