This is a piece of natural opal polished i purchased on my last trip to Banten. It is a opalized wood fossil and a top specimen.
This stone is volcanic in origin. It is a common practice here for miners to heat the rough in sand to remove the clay which sticks to the rough and when polished they add a resin to get a better finish as it hides pits ect.
This materiel loves strong sunlight-it a dim light there is very little colour play.The video was taken under halogen lights.
Top collectors stone.
