Zanazziite is a complex hydrated phosphate mineral from the rosherite group. It is a magnesium beryllium phosphate mineral. Zanazziite arises as barrel-shaped crystals and can reach up to 4mm. It grows along side with quartz minerals. It is found in the crevices of Lavra da Ilha pegmatite, near Taquaral, in northeastern Minas Gerais, Brazil. Zanazziite is named after Dr. Pier F. Zanazzi.
