Measuring roughly 44 centimetres long and about 20 centimetres in both width and height, it is divided into two panels by a vertical incised line. The eastern half has suffered damage and the surface is largely broken away. What survives in the western half is a carving so worn and ambiguous that those who have examined it closely can say only that it appears to take the form of a "Y" shape, resting on a horizontal roll-moulded base, and that it may represent a stylised flower. That hesitant "may" says a great deal about how much medieval carvers can still withhold.

The fragment sits within the ruins of Aghadoe church, near Killarney in County Kerry, a site layered with early medieval material. Its immediate neighbours on the chancel wall are an ogham stone to the west, ogham being an early Irish script in which letters are encoded as notches and strokes along a central line, and a carved crucifixion plaque to the east. That this small, ambiguous block should find itself between two far more legible objects only deepens the sense that it belongs to an older, less resolved chapter of the site's history. Roll moulding, a simple cylindrical or rounded decorative profile common in Romanesque stonework, appears here as a base element, which may suggest the carving once formed part of a larger architectural scheme, though what that scheme was remains unknown.
