Rough (Raw) Australian boulder opal matrix from $12.00 USD to $100.00 USD.
These rough Australian boulder matrix opals, are a variety of Australian opal only found in Queensland. They are natural.

The rough ones will show better their colours when wet or after they have been finished.
All the colours have not always been captured by the camera.
