Quartz (Var: Chalcedony)
This is a (human) brain-sized, natural formation of coral that has been pseudomorphed inside by gleaming chalcedony. There are other examples of pseudomorphs of minerals after organic matter, including (of course) petrified wood. But this has to be one of the more dramatic.
