A marquis shaped Boulder Opal from Queensland, Australia, with fossilized host rock and flashes of white 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.
