The Nun's form brings to mind a female with a quasi-religious and hieratic bearing. The enveloping cape adds an air of mystery.

In a few strokes, the artist has carved an oval pebble to represent the body of a woman, whose arms merge into the outer mass of the pebble. Some of the more discernible elements are a featureless face set off by fine lines from the hair or a headdress, which itself contains very fine incisions; a demarcation of the lower jaw, which sets off the shoulders; a rounded torso and abdomen in which the breasts and navel are suggested by small nicks; and a pubis rendered by a series of lines, which end in a single line marking the crotch.

Also significant are the incisions on the polished back of the pebble, which hint at the presence of a second figure. Finally, a perforation at the base of the chin indicates that the object may have been used as a pendant.
