Manganvesuvianite is a rare mineral with formula . The mineral is red to nearly black in color. Discovered in South Africa and described in 2002, it was so named for the prevalence of manganese in its composition and its relation to vesuvianite.
==Occurrence and formation== Manganvesuvianite crystals occur as long prisms up to . Small crystals are transparent and red to lilac in color; large crystals are opaque and nearly black in color with dark-red internal reflections. Strongly zoned crystals less than in size constitute rock-forming manganvesuvianite.
