Hematite : Fe₂O₃
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina An exquisite specimen from the new find of hematite pseudomorphs after magnetite crystals. This large specimen has rectangular shape with octahedral termination and elaborate hoppered growth on all 4 sides. One of the best specimens I have from this find Overall size of mineral specimen: 6x2x2 cm. Size of individual crystals: 6 cm.

Hematite : Fe₂O₃, Magnetite : Fe²⁺Fe³⁺₂O₄
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina 8.3 x 3.1 x 2.3 cm. This one, for the size, floored me as one of the most elegant examples. A cluster of small octahedrons of lustrous , dark metallic hematite after magnetite forms the base for an elongated, hoppered crystal measuring 6.25 cm in length, which is crowned by a tiny octahedron. Stark and beautiful contrast of different crystal forms ...

Hematite : Fe₂O₃
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina Sharp, well defined specimen from the new find of hematite pseudomorphs after magnetite crystals. The cluster is all sharp octahedral crystals in branching formation. Fully crystallized on all sides - no point of attachment. No damage. Overall size of mineral specimen: 4x2x2 cm. Size of individual crystals: 4-15 mm.

Hematite : Fe₂O₃, Magnetite : Fe²⁺Fe³⁺₂O₄
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina 8.0 x 5.5 x 4.2 cm. Perfect floater! Resembling the letter “T”, this stunning metallic pseudomorph of hematite after magnetite features several sharp, very lustrous, octahedrons to 2.5 cm across perched on an elongated stalk. This is a pristine floater, complete all around, with better lustre in person than appears here.

Hematite : Fe₂O₃, Magnetite : Fe²⁺Fe³⁺₂O₄
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina 4.7 x 4.7 x 3.3 cm. A superb, aesthetic and pristine cluster of ultra-sharp and scintillating hematite pseudomorphs after magnetite from the well-known 2002 find in Argentina. These artistic pieces came from a volcano in a national park, where collecting is strictly prohibited. Supposedly. Anyways, this is a superb piece and who knows when more ...

Hematite : Fe₂O₃, Magnetite : Fe²⁺Fe³⁺₂O₄
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina A novelty this year in Munich, because it is from a very recent find. Parallel growths of octahedral crystals, pseudomorphs after Magnetite, very well defined, bright, with skeletal forms and partially covered by a second generation of small laminar crystals of Hematite. Volcán Payún Matru, Malargüe, Mendoza, Argentina. Specimen size: 7.5 ...

Hematite : Fe₂O₃, Magnetite : Fe²⁺Fe³⁺₂O₄
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina 8.0 x 4.9 x 4.7 cm. Spectacular! This is a single, HUGE, octahedral crystal that also exhibits major hopper growth. It is also a complete floater and is doubly terminated. The luster is top shelf and the whole dark metallic specimen sparkles with a secondary druse of hematite capping the pseudomorph itself. For stark geometry, this one leaps out.

Hematite : Fe₂O₃, Magnetite : Fe²⁺Fe³⁺₂O₄
	Payún volcano, Altiplano de Payún Matru, Mendoza, Argentina 7.9 x 5.1 x 3.1 cm. This is a complete floater that features several stacked octahedrons of lustrous, dark metallic hematite after magnetite. The octahedrons reach 2.5 cm across and if you observe carefully, the three crystals on top of the stack exhibit incipient hopper growth though not so much that they mar the octahedral form as yet. This is a ...
