This is natural rough mined in Lightning Ridge, NSW that has been rubbed back to display the potential stone. These rubs should cut nice stones but will require some cutting skill.
We price our opal based on what we expect the rough will cut as a stone wholesale. If your not happy with it return it for a refund provided its not touched in any way.
All stones are unpolished. I have added water to the surface of the stone to bring out the colours of the Opal.
