This piece of Koroit boulder opal has a small, clear, opalescent rock trapped inside the slice. The boulder is part polished, there is also a red bit on this one. It's small but it is there.
This rough opal is a pretty piece at a low price. It came from a jar of opal I picked up from the Two Skies guys at the gold panning championships.
