Here is a fascinating Opal. This is matrix Opal and it is an old and not well known material. It is a more porous opal found in the mining fields of Andamooka. Matrix comprises precious opaline silica as an infilling of pore spaces in silty claystone. It generally shows fine pin fire colors in its natural state. The matrix opal is cut and polished, soaked in a sugar solution and then boiled in sulphuric acid depositing carbon in the available pore spaces which enhances its color. This type of matrix opal was exclusively found at Andamooka, but is no longer being mined. This stone displays stunning pin fire flash of red and purple/blue with some minor greens. It also has a patch of crystal Opal (White) mixed into the Matrix. This piece would look stunning in a piece of jewelry, particularly a pendant. Enjoy!
