The famous Virgin Rainbow Black Opal is for sale here!
Matrix Opal
Andamooka matrix is a very porous opal which when mined is light in colour. It is cut and polished then carbonised by treating it with sugar and sulphuric acid. The end result is a stone which looks very much like good black opal. It has a characteristic salt and pepper look and can be easily identified when looked at under a magnifying glass.
Matrix opal can also be formed naturally where the silica has run into the minute cracks and crazing in ironstone boulder and this form is known as boulder matrix
