Buy Indonesian Opal Specimens

Natural rough opal potch wood, which is also volcanic, is mined in Indonesia, and it is olive green colour to brown hues and has no treatment.

Black volcanic Indonesian opal is mostly treated.

The opal miners wrap this opal in aluminium foil and then heat to cook the opal and add oil, so the oil penetrates inside the specimen.

This cooking process also makes the sticky clay drop off the opal specimen.

This treatment is not permanent

These opal specimens do look attractive with glass vale filled with glycerine to help enhance the colour

Our sellers from Indonesia will list in description if the opal is treated.
