Manganvesuvianite
Named for the relationship to vesuvianite and for the dominance of manganese in the chemical composition. A rare mineral found in South Africa at the Wessels mine as crystals in veins and vugs, and at the N’Chwanning II mine, the type locality, as a rock forming mineral in association with grossular and xonotlite. Also found in the Harstigen mine in Varmland, Sweden. Manganvesuvianite forms as red to lilac and black prismatic crystals.
