A free-form polished Boulder Opal from Queensland, Australia with seams of precious white and black opal. Boulder Opal forms within cavities of ironstone boulders and fossilized sandstone. It was formed when silica-rich water seeped down into fissures of the host rock and slowly solidified into spheres of opal over millions of years.
