This is a really unusual specimen. A crystal of calcite is perched atop, or impaled by, a stalactite of colorless quartz upon which, are several small lemony-yellow botryoidal fluorite spheres. Encrusted around the calcite core atop the pedestal are rhombs of calcite, to 3 cm across. As some of the calcite seems to hav ealtered to quartz at the surface, it appears that there has been at least, partial replacement(pseudomorphism) of the whole specimen by a later generation of quartz. UNUSUAL! this piece is pristine and complete all around, too
