Sandstone Opal Matrix Polished Sphere Specimen
The Opal Specimen's surface is full of blue, red and green opal colours that glisten and sparkle upon movement. It has been expertly shaped into a Sphere.
For those who like to collect spheres this is a unique specimen to have in your collection.
This stone has been cooked in oil to enhance the Opal colours inside.
Fairy Opal is the name given to natural sandstone opal matrix that has been cooked and burnt with cooking oil to blacken the sandstone, which in turn, makes it easier to see the opal colours.
