This stone comes from the Opal mines at Coober Pedy, South Australia. It is a well-polished natural and it is showing good fire of Blue Green Orange Red and it is ready to be set in a pendant or ring.
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.
