This is natural rough mined in Lightning Ridge, NSW (map). It has some nice colour showing
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.
All stones are unpolished. I have added water to the surface of the stone to bring out the colours of the Opal.
