This is a piece of natural opal polished I purchased on my last trip to Banten. It has been cut on the opal field there. It is a common practise to heat the rough in oil and sand to remove the out clay which sticks to the opal rough.This is a untreated stone but i suspect if tested there will be traces of baby oil.
This stone is considered to be a black opal with a body tone rating of N1
This stone is volcanic in origin.
This stone loves strong sunlight
