2.2" Sparkling Hausmannite Crystal Cluster - South Africa
This is an outstanding cluster of shinning hausmannite crystals on a coal-black matrix. 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 coloration that can be found in other minerals and rocks. The chemical composition of hematite 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.
