These are a pair of Solid White Coober Pedy natural Crystal Opal. These come from the mines at Coober Pedy in South Australia. They have been cut to form two stones which can be used set as earrings. They show a very nice amount of colour on both sides of the stones
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.
