The slab is modest in scale, just 54 centimetres tall, 24 centimetres wide, and only 4 centimetres thick, yet its presence in Raheen carries the quiet weight of displacement, of an object that has travelled far from the context in which it was made and used.

The slab was one of two cross-slabs lifted from the paved floor of what researchers identify as Cell A, a clochan, that is, a small dry-stone beehive hut, situated to the north of the church within the High Island monastic complex. It is cut from garnet mica-schist, a metamorphic rock with a faintly glittering quality, and shaped into a cruciform outline. The foot is broken obliquely and the right side has sustained damage, but one face retains a carved Greek cross, the equal-armed variety, rendered in a simple linear style and now considerably weathered. The form of the slab itself, shaped to echo the cross rather than merely bearing one as decoration, places it within a tradition of early medieval Irish stone carving in which the object and the symbol it carries are unified. Fisher's 2014 study catalogued it alongside comparable material, and White Marshall and Rourke had documented it earlier in 2000, situating it within the broader body of carved stonework associated with High Island's monastery.
