This limestone block, just 1.2 metres tall, has been shaped or selected with unusual precision: rectangular in plan, with a flat top that slopes gently downward toward the north-northwest. It sits in a level area of gently undulating pasture, unannounced and without obvious ceremony, oriented along a NNW-SSE axis in the manner of many prehistoric standing stones across Ireland, where alignment with landscape features or celestial events is often suspected but rarely confirmed.

The stone measures 0.51 metres by 0.22 metres at its base, compact dimensions that give it a more deliberate, almost worked quality compared to the rougher uprights found elsewhere in Tipperary. Limestone, the dominant bedrock across much of the county, weathers slowly and holds its edges well, which may help explain how clearly defined the stone's rectangular form remains. Beyond its physical description, the historical record for Lisduff is spare. No associated earthworks, burials, or finds are documented in the immediate vicinity, leaving the stone to stand on its own terms, as so many of these monuments do, without a narrative attached.
