This is a solid Boulder Matrix Opal from the Yowah opal fields in Queensland. This is a well-polished stone which has unusual patterns imbedded in the natural chocolate brown ironstone. This is fitted with a black pendant cord so it can be used as a pendant straight away.
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.
