While the diptych panels are ivory, bone was used along with wood for the inlaid case. The ivory panels are in remarkably good condition. Traces of gilding noted by Du Sommerard in 1846 have survived (or been renewed), especially on the haloes. Metal nails pierce the hands and feet of Christ in the Crucifixion. The background, of wood coated with parchment, is polychromed, with blue decorated with gold stars, rays or swirling patterns behind the narrative scenes, and brownish yellow behind the architectural borders and figures on the sides.
A strip of ivory 9.8 cm long has come off the top border on the left. Ivory bands on the edges are loose in many places. The intarsia is warping on the exterior at the bottom of the recessed inner panel on the front. Some checkerboard portions of the intarsia are inlaid, others painted.
