Its dimensions, roughly 27 to 33 centimetres wide and 74 centimetres tall, make clear without any inscription that it once marked the burial of a child. That quietness is part of what makes it arresting: no name, no date, only the stone itself and the cross cut into its face.

The slab, made from sandstone or granite, carries an incised cross of a type with a long history in Irish funerary and ecclesiastical carving. The cross has a stepped base, where the shaft rises from a series of graduated tiers, and a ringed head, the distinctive circle connecting the arms that is sometimes called a Celtic cross, though the form predates that label by many centuries. It sits attached to the northern end of what appears to be a later inserted wall within the chancel, suggesting the church saw significant alteration over time and that this small marker survived, or was repositioned, through those changes. The slab is recorded as complete, which is itself notable; many comparable stones have been broken, reused as building material, or lost entirely.
