It rises about 1.6 metres from the ground, irregular in shape, neither especially tall nor elaborately placed. What lifts it out of the ordinary is a small, tantalising discrepancy between what it is and what it may once have been described as being.

A 1938 entry in the Schools Manuscript, a nationwide collection of local folklore and knowledge gathered by schoolchildren across Ireland, recorded a stone near Farranfore as standing six and a half feet high and bearing the prints of a man's hand pressed into the rock. Whether those impressions were natural formations read as something more, or whether they have since weathered away, is not known. When the Killeagh stone was examined as part of the Castleisland District Archaeological Survey, no markings of any kind were found on its surface. The stone may be the same one, or it may not be. The measurements are close but not identical, and the distance between the two places is short enough that the identification remains plausible without being certain. Standing stones of this kind, single upright boulders set into the ground, appear throughout Kerry and the wider Irish landscape, and while many date to the Bronze Age, their original purposes, boundary markers, ceremonial points, memorials, are rarely recoverable with confidence.
