The pendant is oval in plan and rectangular in section, made of three components, two sheets of silver cut in an oval shape, one soldered onto a length of a rectangular silver sheet that acts as the side of the pendant, and which has an integral hinge mechanism for the opening side of the locket, and an integral suspension loop.
The top, hinged face has a border of circumferential grooves with radiating triangles incised over them. The face bears an incised I H S, in which the uprights of the I and H are broad with further incised oblique lines within them. A cross with an extended lower limb and the other arms flared is positioned above the H, with the lower limb resting on the cross bar. Below the IHS inscription are three motifs radiating from the base of the central panel. They look like lily trumpets or crystals, and are depicted in three dimensions. They may be intended to be rays of light or the nails that crucified Jesus. The front face is slightly bent inwards. The opposite (back) face is has a border which matches the front. Across the centre are the letters MRA, with the uprights of the letters broad and filled with oblique lines. A crown is depicted above the letters. The side of the locket is moulded into a central rounded ridge flanked by a groove on each side; a reel shape. There is a circular hole in the base of the side, opposite the suspension loop. This hole has an internal screw thread. The suspension loop is circular, slightly bent forwards, and has a very small knop at the apex.
