Nice geode completely lined by black lustrous crystals of manganite and pirolusite. Apparently, samples from Imine are indeed original manganite crystals mostly partially (not completely) replaced by pirolusite crystals. Nice aesthetic cavity specimen, not so common in the locality.

Acquired in 23/6/2012. Ex Gustaf collection #1691, with his handwritten label.
