An amazing and perfect wheat sheath formation of stilbite is fully formed and stands upright on end in a dramatic fashion. The matrix is a tholeiitic basalt vesicle covered with what looks to be white mordenite. The stilbite top termination shows very pointed and sharp tips. This is just a very perfect example of a rather common zeolite mineral.
