Item Information

Dimensions (mm) 15 x 13 x 4mm
Weight (carats) 4.5 carats



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
