Boulder Opal  This dark opal is found in Western Queensland and it forms naturally on its host rock of ironstone, which is cut to form part of the gemstone. Boulder Opal occurs as thin veins in sedimentary ironstone boulders. The colour layer is naturally part of the dense brown ironstone base and is inseparable from it.
