The Opal Specimen's surface is a stunning display of Red, blue, green and hints of yellow glittering Opal Colours.
A beautiful looking natural pattern makes this specimen quite unique.
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
