What makes the sandstone slab now held at South Tipperary County Museum quietly remarkable is how many small departures it makes from the norms of its own tradition. It was recovered from the fabric of the south wall of the nave at a medieval church in Cloneen, set immediately east of the doorway, where it had been incorporated into the masonry at some point in the building's long life.

The slab survives in two pieces, with a third middle section now lost, though its original dimensions can be estimated at roughly 1.8 to 1.9 metres in length, tapering from about 0.50 metres at the top down to 0.17 metres at the base. The coffin shape itself was standard enough for the period, and the surface carries an incised six-armed floriated cross, a type of ornamental cross whose arms terminate in plant-like forms, in this case fleur-de-lis symbols. A small knop, a rounded boss or protrusion, sits halfway up the shaft. Of the four diagonal arms that would originally have carried fleur-de-lis terminals, only two partial examples survive, and these are notably asymmetrical: the terminal on the left side of the cross is considerably larger than the one on the right, a discrepancy that seems to have been cut deliberately rather than resulting from damage. More unusual still are the two horizontal arms, which end in plain rectangular terminals rather than the floral forms one would expect. Most medieval graveslabs of this type also carry a chamfer, a bevelled edge, running around their perimeter. This one instead has a roll-moulding, a rounded raised border, which is rare in the genre and may indicate that the slab originally served as a lid for a stone sarcophagus rather than a simple cover for a slab-lined grave. The style of the fleur-de-lis, the roll-moulding, the tapered sandstone form, and the overall design together suggest a 13th-century date.
