Opal Rough Description: Rough boulder opal from the Winton Australia field featuring green-blue striped opal. This opal, of course, could be cut and polished as a pendant or ring stone but it has been left as it was found in the ground for the purpose of collection of unusual and unique, never to be repeated pieces.
Boulder opal is an opal that is sliced out of large ironstone boulders where veins of opal color are found. This requires the help of (sometimes) large diamond saws and sledgehammers.
When the pieces containing the color are separated from the mother stone, the opal cutter will then gradually clear the waste away from one side of the veins of opal, exposing the color of the stone.
More often than not the color has lots of ironstone inclusions giving it an evidence that it is a natural opal. Sometimes the full color of the opal is exposed and stones like this are very similar to black opals. They are called ‘ full-color boulder opals’.
