1.8" Lustrous Manganvesuvianite Crystal Cluster - South Africa

Manganvesuvianite is a deep red-black, manganese-rich variety of normally greenish vesuvianite. These tetragonal silicate crystals are exemplified by the type locality from the N'Chwaning Mine in the Kalahari Manganese Fields of South Africa. Manganvesuvianite shares physical characteristics with vesuvianite--both appear as well-terminated prismatic crystals--but thier colors are significantly different.
