Boulder opal

Boulder opal is the most organic type of gemstone. Being an opal that has a host-rock, the boulder opal forms in veins, fissures and cracks in the ironstone. The opal moves with the cracks in the ground, making it undulate, so the face of a cut and finished boulder opal will not usually be even faced or domed.
