What is Hausmannite?
Hausmannite is rich in magnesium and occasionally appears as a genuinely captivating gemstone. When processed through Ferro manganese refining, it creates a dark brown color for pavers and bricks. In nuclear applications, hausmannite is used to promote proton travel, but only when dissolved in water. Specimens are highly collectible and range wildly in price.
Etymology & Origins
Wilhelm Haidinger (1827) named it in honour of Johann Friedrich Ludwig Hausmann (1782–1859), Professor of Mineralogy, University of Göttingen, Germany.
