Black Matrix Australian Opal is an interesting gemstone from the Andamooka mine, Australia. In its composition, it is a "matrix" – a duet of sandstone and opal, due to which the stone sparkles with many small rainbow dots. Matrix opal is completely opaque and has a black background color. The cabochon shape is traditional and recognizable for specimens from Australian deposits – "free form".
