Huge 240.72ct black opal rough piece

240.72ct black opal rough

This is a huge 240.72ct opal rough piece. It will cut many multi coloured white opal stones or one very large chunky one. There is a bar of green on one side and a very interesting bright red/orange bar on the other. This has some darker potch on the outside of that. It appears the red bar goes all the way around the piece. I don’t think this will be gem quality but it still looks fairly bright. There are some sand inclusions but they don’t appear to penetrate into the piece very far at all.
