This is a Koroit Matrix Opal Stone which comes from the Koroit Opal fields of Queensland, Australia. The stone has been drilled and a Bail could be fitted at a small extra cost. I shows Purple & Blue fire set in a Matrix in brown ironstone
If you see an opal on this website that you might like to have as a pendant, please contact Peter to discuss if it is possible with that particular stone.
You also need to state if you wish to have a bail fitted or not. If you do, then you would need to be charged for the cost of metal, silver or gold.
