Maxixe Mine (José de Linto claim), Piauí Valley, Taquaral, Itinga, Minas Gerais, Southeast Region, Brazil

Li-Cs pegmatite.
Famous for a find of deep blue maxixe/maxaxite aquamarine in 1917. Unfortunately the color quickly faded to a whitish yellow after exposure to light. The color is probably caused by the replacement of a missing atom by a vibrating electron in the lattice creating a color center, caused by natural radiation.
