Payun Volcano, Altiplano de Payun Matru, Mendoza, Argentina.
Another great cluster, large octahedral crystals to 25 mm across sparkling and beautiful, a top miniature from a volcano in a national park in Argentina. The supply of the specimens is very limited since any collecting in the park is strictly forbidden. It is much better in person; the picture does not reflect the real beauty of this great masterpiece.
