2.2" Hausmannite Crystal Cluster - N'Chwaning Mine, South Africa

Hausmannite Crystal Cluster - N'Chwaning Mine, South Africa #220041

This is an outstanding cluster of shinning hausmannite crystals on a coal-black matrix. A small cluster of calcite can be found in association with the hausmannite. The entire specimen measures 2.2" wide and was collected from the N'Chwaning Mine in the Kalahari Manganese Fields of Kuruman, Africa.

Hematite is a fairly common mineral, typically responsible for the red-brown colorations found in other minerals and rocks. Its chemical composition is Fe2O3, occasionally containing small amounts of titanium (variable formula (Fe,Ti)2O3). Much of the time, non-crystalline hematite specimens are the result of a transformation from limonite following loss of water.
