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.
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.
The Opal Sheriff program allows our members to request an audit on any auction, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
