What was once a marker on a south-facing pasture slope in Ballyheen Middle is now a 1.5-metre length of irregular quartzite lying beside a field fence, roughly thirty metres from where it originally stood. It was removed, presumably during agricultural work, and has remained recumbent ever since.

The stone's absence from Victorian-era mapping suggests it was either overlooked by surveyors or already considered unremarkable by the mid-nineteenth century, though the site clearly carried local significance well into the twentieth century. Writing in 1934, a researcher named Bowman recorded a folklore tradition connecting this stone to a nearby companion stone: the two were said to have landed in their respective positions after a pitched battle between two giants, each hurling the great quartzite blocks at the other. Quartzite, a hard metamorphic rock with a faintly glittering surface, would have made a vivid impression on people encountering it in the landscape, and it appears with some frequency in Irish prehistoric monuments, possibly because of associations between its brightness and particular ritual meanings. Whether that explains the original erection of the Ballyheen stone is unknown, but the giant-battle legend at least preserves a memory that these were not ordinary field stones.
