Gymnocalycium monvillei grows individually, rarely sprouting, with dark green, spherical to flattened spherical shoots that reach heights of 6 to 8 centimeters with diameters of up to 20 centimeters and form a massive taproot . In old age, the plants sometimes briefly become columnar. The 10 to 17 wide, blunt ribs are clearly divided into bumps with noticeable chin-like protrusions. The areoles are oval and, in addition to the thorns, have a dirty, whitish wool felt. The strong, thick, slightly curved thorns are yellowish and have a reddish or purple base. There are one to four central spines with a length of up to 6 centimeters, which can sometimes be missing. The 7 to 13 radial spines are 3 to 4 inches long.

The white, red-tinged, partially monoecious flowers reach a length of 3 to 8 centimeters and have a diameter of 4 to 9 centimeters. The stamens are whitish with yellow pollen , the stylus is whitish yellow. The spherical fruits are green to cloudy orange-red and reach a diameter of up to 2 centimeters.
