Only the lower portion protrudes above the ground, roughly 70 centimetres of stone tapering slightly from 27 centimetres wide to 25 at the base, and just 7 centimetres thick. Carved into its face is an incised cross-shaft ending in a fleur-de-lis terminal, the stylised three-petalled motif more usually associated with heraldry and decorative metalwork than with rural Irish gravestones. It sits at the north-eastern end of the graveyard, east of a modern Celtic cross dedicated to Patrick Phelan, the contrast between the two markers quietly illustrating several centuries of how communities have chosen to commemorate the dead.

This slab is one of four tapering graveslabs recorded in the graveyard, all of them associated with the medieval church at Ballycallan. The historian William Carrigan noted the group in his 1905 history of the diocese of Ossory, and all four appear to date from the 13th or 14th century. Tapering slabs of this kind, broader at the head and narrowing toward the foot, were a common grave-marker form across medieval Ireland and Britain, often left plain but sometimes carved with a cross, a sword, or as here, a more ornamental symbol. The fleur-de-lis as a terminal motif suggests a degree of craft ambition; whoever commissioned or cut this stone was working within a decorative vocabulary that connected provincial Kilkenny to wider European artistic currents of the period.
