Hausmannite from N'Chwaning II Mine, South Africa
from N'Chwaning II is one of the rare cases where a black manganese oxide becomes a true connoisseur mineral. The best pieces are not simply “black crystals”: they are architectural, high-luster, jet-black to brownish-black dipyramids, often stacked into pagoda-like forms and set against brick-red andradite, white baryte, colorless to white calcite, or the prized rose-pink datolite that made certain late-1990s pieces instantly recognizable. In hand specimen, the finest crystals have a sharp metallic to submetallic gleam that catches light from multiple growth faces, so that a seemingly dark specimen suddenly breaks into bright reflections as it is turned.
