This is natural rough mined in Wyoming field Lightning Ridge, NSW (map). The rough has been tumbled to remove the sand and expose the opal. It will be fun to cut but a bit frustrating when you cut a small stone with nice colour.
Weight app: 2.10 cts
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.
