System:OrthorhombicHardness:2½ - 3½
Name:From the type locality near Guanajuato, Mexico.


Easily distinguishable from the more common (in Guanajuato) Paraguanajuatite if macroscopic as the latter has platy/foliated aggregates with perfect cleavage whereas Guanajuatite resembles minerals of the stibnite group.
