Magnetite

MagnetiteTypically, the Magnetite specimens from this locality are closely grown together, and this is a great example of said material. The piece has fine, good sized, sharp, lustrous, black, metallic, "Alpine type" octahedra (some are twinned) associated with cream colored Feldspar on matrix. Great quality for the species and the locality, and the faces on the Magnetite crystals are rather smooth and shiny. Keep in mind that there are no other localities

The species was named after Basilius Valentinus
