Measuring roughly 28 centimetres by 20 centimetres and barely five centimetres thick, it is a modest object, yet its surface carries a Latin cross rendered in low relief, with irregular hollows worked into the angles of the cross arms and a delicate incised ring at the centre. The back of the stone remains hidden, set against a ledge inside an oval enclosure.

St. Berrihert's Kyle is an early ecclesiastical site, a kyle being a small wooded enclosure associated with a holy person or hermit. The oval stone enclosure that now protects the collection of slabs was constructed in 1946 by the Office of Public Works, built with stepped internal sides to display the stones in an organised way. The cross-slab in question is catalogued as slab 25 in Ó hÉailidhe's 1967 study of the site, which remains one of the more detailed examinations of the Kyle's collection. The combination of the hollowed angles and the central ring places this piece within a recognisable tradition of early medieval Irish stone carving, where geometric and symbolic elements were worked into relatively small, portable or locally placed slabs rather than large architectural monuments.
