It measures just 38 centimetres by 33 centimetres, barely larger than a sheet of paper, and is only four centimetres thick. What makes it quietly arresting is not its size but its detail: the cross carved into its face has equal arms terminating in T-bar finials, a style associated with early Christian stonework in Ireland, where such terminals were a way of giving the cross arms a weighted, finished appearance. Whether this stone is genuinely early medieval or something later made in an older manner is, as yet, unresolved.

The stone came to light during a graveyard survey conducted by Laurence Dunne in 2010, which recorded fourteen previously unnoticed cross-slabs and cross-inscribed headstones at Garfinny. The group divides into categories: eight small unhewn stones with simple incised crosses, five more formally cut slabs datable to the eighteenth or nineteenth century, and one later standing cross. Stone 61, as it is catalogued, belongs to the unhewn group, its purple sandstone unworked except for the carving itself. Dunne also noted a possibility of faint lettering beneath the cross, though this could not be confirmed. That ambiguity, combined with its uncertain date, leaves the stone sitting somewhere between the early Christian and the post-medieval, an object that resists easy classification and has not yet given up whatever it might say.
