he Sturmanite of the Kalahari Manganese Fields originates primarily from N'Chwaning I and II mines. These mines have produced some fine specimens, especially during the early 1980's.
Sturmanite usually forms long hexagonal crystals, which are often amber coloured. Other colours include canary-yellow, pale yellow, peach, brown, and colourless.
Physically and chemically, Sturmanite is very similar to Ettringite and Charlesite, both of which are also found in the Manganese Fields. This makes accurate visual identification of these minerals very difficult. To the best of our knowledge, all of the specimens on the right are Sturmanite.
