The somewhat different opal

The Opalmatrix is an opal variety with mixed colors with a dark body-color. It consists of a honey colored mixture of opal, sand, kaolin and clay particles. Apart from the natural Opalmatrix you will also find the treated Opalmatrix. Since this opal material is fine porous, Opalmatrix ist the only opal which can be easily treated. Not the opal is changed by the treatment, but the color of the matrix changes. The Opalmatrix is treated with a sugar solution, which is then carbonized. After the treatment, the opal sometimes looks very similar to the Black Opal.
