It is not a dramatic monument by any conventional measure, standing just over a metre tall, but its quiet regularity is part of what makes it curious. The stone is a neat rectangular block, oriented along a NNE-SSW axis, and its dimensions are precise enough to suggest deliberate shaping: 1.08 metres in height, 73 centimetres wide at the base, and only 25 centimetres thick. It is, in the language of field archaeology, a standing stone, one of the most common yet least understood monument types in the Irish landscape.

Standing stones were erected across Ireland from the Neolithic period onwards, though most are thought to date from the Bronze Age. Their purposes remain genuinely unclear, and interpretations range from boundary markers and memorial stones to astronomical indicators and points on ancient routeways. The Iveragh Peninsula, the long southwest-pointing finger of Kerry that includes the Ring of Kerry, is particularly rich in prehistoric monuments, and this stone in Gearha sits within that broader landscape of ancient activity. The site was recorded and described by archaeologists A. O'Sullivan and J. Sheehan in their 1996 survey of South Kerry, which remains a key reference for the prehistoric and early historic archaeology of the region.
