The crystals (1)
were discovered 1995 in the NW-walls of the the Pizzo and at the slopes in
direction Rina Grande. The mineral of the pyroxene-group, is shiny green and
reach the hardness of 5-6. Assuming that the stiffing- temperatur is a
little higher than the strombolian- magma, the crystals are "swimming" in a
solid condition in the liquid, until they get ejected to the surface.
