It is relatively modest in size, measuring at least 62 centimetres in length and just 18 centimetres wide, but its western face carries a Latin cross carved in false relief, meaning the cross is not raised from the stone but rather defined by a shallow groove cut around it, leaving the cross itself flush with or very slightly proud of the surface. The groove widens at four points where the vertical and horizontal arms of the cross meet, forming small circular depressions that give the whole composition the appearance of a ringed cross, the type more commonly associated with freestanding high crosses elsewhere in Ireland. At the exact centre of that intersection sits a tiny circular dimple, barely two centimetres across. The upper portion of the shaft tapers outward as it rises toward the top of the stone, with a slightly hollowed centre that draws the eye upward to a gently expanded terminal. The cross itself is at least 44 centimetres long, though the base disappears below ground level, so its full extent is unknown.

The graveyard appears on the 1838 Ordnance Survey six-inch map under the name Kilfian, a placename that suggests a dedication to a saint named Finian or a variant thereof, several of whom are associated with early Irish monasticism. The cross-slab sits in the oldest part of the burial ground, at the southern end of a walled extension added in the twentieth century. The stone itself, sandstone and rectangular in cross-section, is the kind of marker that belongs to an early medieval tradition of inscribed grave slabs and boundary stones found across Ireland, simple in ambition but carefully executed. The armpits at the crossing of the arms are a detail that occurs on other early Christian stonework in the country, a small flourish that hints at a carver working within a recognisable, if local, tradition.
