The conch shell is very delicately carved in shallow relief on the exterior. The main register depicts seven manifestations of the Buddha, seated in dhyanasana (a meditation sitting posture) on a double-lotus throne. Each Buddha holds a different mudra under the bejewelled curtain, bordered above and below by a band of overlapping lappets. The concentric rings of the shell are further decorated with beads. The tip of the shell is hollowed with a circular aperture. The edges of the shell are finely carved with a narrow band of interlocking stylised florettes. The interior is incised with a Qianlong six-character reign mark in a line and a long poem written in four-character stanzas, followed by Qianlong Yuzan, ‘By Imperial order, praised by the Qianlong Emperor’ and two seals, guxiang and taipu (ancient fragrance, uncarved jade).
