This is natural rough mined in Lightning Ridge, NSW (map) that has been rubbed back to display the potential stone. This rub will cut a nice stone as it is already shaped. Perfect for a new cutter who wants to practice on some more expensive material
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.
There are some good opal cutting tips in the forum section on Opal Auctions.
This stone is unpolished. I have added water to the surface of the stone to bring out the colours of the Opal.
