The object has moved, but the carving has not changed, and what survives is remarkably layered for something so compact.

The slab originally came from High Island, a small and largely inaccessible island off the Connemara coast that was home to an early Christian monastic settlement. The stone itself is garnet mica-schist, a metamorphic rock with a faintly glittering surface, and it measures 0.72 metres high by 0.53 metres wide. On its north face, a Latin cross is carved in high relief, framed by a band that encloses a double-banded cross within it. At the top terminal of the cross sits a triquetra, the three-cornered interlaced knot used frequently in early medieval Christian art to suggest the Trinity. A boss, or raised rounded projection, appears in the upper left quadrant. The south face is more worn, but carries a linear cross set within a double roundel, with crosslets, small subsidiary crosses, marking each terminal. The left arm of the slab, on its flat surviving edge, repeats the motif once more: another linear cross, again with crosslet terminals. The repetition across faces and edge suggests a carver working deliberately, covering the slab as a complete devotional object rather than treating one side as primary. Fisher's 2014 study places it within a documented group of High Island cross-slabs, identifying it by number and illustration.
