Vesuvianite (Kalahari Manganese Fields, South Africa)
N'Chwaning 2 Mine, Kalahari Manganese fields, South Africa. 35mm across, 20mm deep, 20mm high.
We have it on good authority that the blue material is Vesuvianite, on a trip to a well known collector from this area we acquired a number of these specimens and have since then never seen any again. They are rather different and quite unique from the Kalahari Manganese Fields. Estimated packed shipping weight +/- 150gr.
