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 variations of black opals. They are called ‘full color boulder opals’ this one you can use for abstract boulders.
