One side bears a cross in low relief with a solid ring at its centre, inside which a further ring has been incised; the other presents an outlined Latin cross defined by a sharp, precise line cut into the stone. That two distinct designs occupy opposite faces of a single modest fragment gives the object an unusual density, as though the carvers were reluctant to leave any surface unmarked.

The slab belongs to the site known as St. Berrihert's Kyle, an early ecclesiastical enclosure in the Glen of Aherlow. The Kyle, a word derived from the Irish for a narrow wood or corner of land, preserves a collection of early medieval carved stones associated with the obscure local saint Berrihert. In 1946 the Office of Public Works constructed an oval stone enclosure around the site, stepped internally, to protect and display what survives. The cross-slab catalogued as 6A/6B sits on the wall of that enclosure in its eastern sector, its small dimensions, 0.33 metres by 0.18 metres with a thickness of just over 0.11 metres, belying the care evident in both carved faces. The stone and its companions were documented in detail by Ó hÉailidhe, whose 1967 study remains a key reference for the group.
