Andamooka Rainbow Matrix Opal

Andamooka matrix opal is a treated opal. The rough is soaked in very dense sugar solution and then heated in sulfuric acid. To burn the sugar that has saturated into the opal giving it the appearance of a dark or black opal. The stones we offer have also been sealed with a clear hard plastic resin. It is hard to get a good picture of either of the stones we offer, so if you can imagine double the color at least you will have a fair idea of the true look off these stones.
