Boulder Opal & Boulder Opal Carvings

AUSTRALIAN BOULDER OPAL. Mineshaft has a large range of Boulder Opal and Boulder Opal carvings. Boulder opal is the term used for opal that occurs in ironstone boulders. The opal infills cracks within the boulder creating a unique type of opal. Peter had two boulder opal mines in Queensland. His Rainbow opal mine provides a lot of the boulder opal in Mineshaft. This has been cut into stones and also used for unique carvings and polished collectables. Click on the images to see a full size picture.
