The Opal Specimen's surface has a galaxy of glittering green Opal Colours along with a unique and beautiful natural opal pattern.
The Sandstone Opal Matrix was mined in Western Queensland near the town of Winton.
In certain areas of Queensland, Opal formed inside Sandstone. To enhance the Opal colours, the Sandstone containing Opal, is cooked in cooking oil, resulting in the sandstone turning grey or black in colour. Cooking the Sandstone Opal Matrix in this way will make the Opal colours more vibrant and make any patterns formed by the Opal layers more visible.
A certificate of authenticity stating that the opal specimen is a Solid Australian Opal is included.
