Hematite pseudomorph after Magnetite-
Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina.

A massive example of this pseudomorph, with many elongated, hoppered crystals. Along with the stunning sculptural form of the original magnetite crystals, in both sharp octahedrons and exquisite hopper growth, this specimen has outstanding luster which is hard to convey in the photos.
