Spessartine Spessartine Spessartine, sometimes mistakenly referred to as spessartite, is a nesosilicate, manganese aluminium garnet species, MnAl(SiO). The mineral spessartine should not be confused with a type of igneous rock (a lamprophyre) called spessartite. Spessartine's name is a derivative of Spessart in Bavaria, Germany, the type locality of the mineral. It occurs most often in granite pegmatite and allied rock types and in certain low-grade metamorphic phyllites.
