This flat Opal piece is partly encrusted with a thin layer of matrix rock. However, much of its surface is fractured, showing a dull vitreous luster and the standard white color of the material. Portions show a colorful iridescence that occurs in layers within the stone- these layers are rather badly skewed, so most of the material would be wasted if one were to try to cut it into a gem.
