It is a large piece of work, tapering from 65 centimetres wide at the top to 45 centimetres at the base, and running to nearly two and a half metres in length, its edges finished with a neat roll-moulding, a rounded ridge carved along the perimeter that gives the whole slab a sense of careful, deliberate craft.

The real interest is in the cross carved across its surface. The cross-head has eight arms and is described as floriated, meaning it blooms outward in stylised plant forms rather than terminating in plain geometric ends. The arms are tipped with fleur-de-lys motifs arranged so that they touch one another, forming a circular outline around the cross-head. Below the head, small leaves push out from either side of the shaft, and a second set of leaves or fleur-de-lys spring further down. The shaft itself is punctuated by two knops, a bulging one where the vegetation sprouts and a circular one just above the base, giving the composition a kind of rhythm as the eye moves downward. At the very foot, two more fleur-de-lys splay outward to form the cross base, so the decorative vocabulary that begins at the top reappears to close the design. The overall effect is of something simultaneously architectural and botanical, controlled but not rigid.
