A 2-sided Boulder Opal from Queensland, Australia that was polished free form, displaying the ironstone matrix and flashes of precious opal seams. 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.
