Fragment with a festoon based on the design of overlapping lanceolate leaves, though reduced to a geometric pattern of diamonds. The rest of the face as well as the underside immediately adjacent to it is decorated with rosettes within filleted lozenges and 1/2 rosettes in the resulting triangles. There is a groove and socket above the side adjacent to the lanceolate festoon with a circular mark, perhaps a mason's mark, next to the socket.
