On the specimen coexist two generations of crystals of Hematite. The first one has arborescent growths of octahedral crystals that are pseudomorphs after Magnetite (the variety Martite). On those octahedrons is formed a second generation of very bright laminar crystals of Hematite. Aside from its mineralogical interest, the specimen is notably esthetic. A very good sample.
