Magnetite : Fe2+Fe3+2O4

Dimensions: 3.3 cm x 3.3 cm x 1.6 cm

3.3 x 3.3 x 1.6 cm. Typically the Magnetite specimens from this locality are closely grown together, but this piece has great isolation between the crystals. These are also some of the finest quality crystals I’ve seen from this locality in a few years. The piece has excellent quality, good size, razor sharp, lustrous, black, metallic, "Alpine-type" octahedra associated with blocky, cream colored Feldspar crystals on matrix. The largest Magnetite crystal measures 1.2 cm. across, which is good size for the locality. This is one of the better quality specimens of this material that I’ve seen from this locality, and most of the crystals are undamaged. Keep in mind, that there are no other localities producing Magnetites of this quality today, and there are few localities in the world that have ever produced Magnetite like this. Though this species is well known to collectors, it is remarkably difficult to obtain such well crystallized, highly displayable specimens like this one. Ex. Brian Kosnar.
