The stone carries an ogham inscription, that early medieval Irish script in which letters are represented by a series of notches and strokes cut along a stone's edge, and it arrived at University College Cork from the Glenaglogh North and Glenaglogh South area, though exactly where within that landscape it originally stood remains unknown.

Scholars have attempted to read what survives of the inscription. R.A.S. Macalister, writing in 1945, and Damian McManus, in a 2004 study, both interpreted the carving as CUNAGUSSOS MA, with the remainder lost or illegible, suggesting a personal name in the genitive case of the kind commonly found on ogham stones, typically recording lineage or ownership of a burial. The stone's earlier context, as a component of a stone circle, is unusual; ogham stones were generally raised in the early medieval period, centuries after most Irish stone circles were constructed, which raises questions about whether the stone was cut and placed within an already ancient monument, or whether the association came later.

The stone is on permanent display in the Stone Corridor at University College Cork, a long gallery that houses one of the more significant collections of ogham stones in Ireland, gathered from across Munster. It sits among others of its kind, legible and otherwise, each one a fragment of a naming culture that flourished roughly between the fourth and seventh centuries AD.
