The fragment, measuring roughly 55 centimetres by 27 centimetres, has two chamfered edges, meaning its corners have been cut away at an angle, a finishing technique associated with dressed stonework in medieval ecclesiastical and secular buildings. That kind of careful shaping was not done for a boundary wall; the stone clearly began its life as part of something more deliberate.

The graveyard at Churchclara encloses the remains of the medieval church of Clara, and the fragment almost certainly originated there or from a structure associated with it. It is not unusual to find worked stones from ruined churches pressed into secondary use in surrounding walls, as communities repaired and rebuilt field boundaries and enclosures over the centuries using whatever material was at hand. What is slightly unusual here is that the piece remains visible and identifiable, its chamfered profile still crisp enough to indicate its origins, rather than having been turned face-down or buried within a wall's rubble core. It rests on the wall surface, almost as if placed there for safekeeping.
