Cristobalite is a rock-forming mineral, and occurs as a transitional silica polymorph in the form of opal-C (opal made of tiny cristobalite spheres) during the diagenesis of sediments made of opaline skeletons of marine organisms. It will slowly be converted into quartz (chalcedony or microquartz) with time.
