TC12 Hausmannite pseudo. after Manganite 
Ilfeld, Harz Mountains, Germany

3.5x 3.4x 2.0 cm

$200

A rare pseudomorph of hausmannite after manganite, from the classic locality at Ilfeld.  These  pseudos are very difficult to obtain, and I have only seen a couple similar pieces for sale.

This specimen is composed of a cluster of elongated, terminated  manganite crystals that have been completely replaced by hausmannite.
