25 ct Free form Andamooka opal cabochon from Australia

  • Sale
  • Regular price $60.00


This is a treated matrix opal from the Andamooka opal fields of Australia. These stones are often mined with a white or cream colored matric and are then treated to give them a darker background. The treatment is considered safe and an industry standard and permanent. The appearance of stones like this is a lot like glitter, pressed into black cement.
