A brilliant thumbnail specimen of mirroring luster, excellent composition and near perfect condition. The early 2000s find at Kamoya is regarded as the best for this mineral species and there really is nothing comparable in sight. The larger crystal on this specimen is 1.3 cm in diameter, sharp and with nice detailed faces. All crystals are of characteristic cuboctahedral shape, nicley developed and of best quality!
The heavy matrix of modified octahedral galena shows excellent metallic luster and sharp crystals up to 2.4 cm in diameter, associated with chalcopyrite and smaller white chalcite. Atop this towering matrix stand several white calcite scalenohedrons up to 5.5 cm long. The outer layer of these crystals is partly transparent and allows a view to the white translucent phantom that lies around 3 mm below the surface. All main crystals are in perfect condition, only the matrix shows some contacts at the back. This is an imposing piece of good quality all around!
A 3-dimensional group of octahedral magnetite crystals has been pseudomorph transformed into metallic grey hematite at the cinder pits near the Payún Matru volcano. This structure is a distinctly 3-dimensional floater specimen that shows characteristic hoppered growth and towering octahedrons. The piece is all undamaged and very much appealing in person!
