Could be common opal (opalized something)? It has that rich brown colr and smooooth texture on the broken face. It is rich!

It has a Coral look to it as I have seen color similar to that under the white coating. Or maybe some sort of odd plant that got preserved.

Would there be any simple ways to test if opal or coral?
