The field of the matrix contains a pear shaped escutcheon bearing the Pisan Cross (A cross with keys, three spheres on every arm) with foliate borders. Within a double fillet the inscription, in Roman capitals, is the inscription: SIGILLVM • POPVLI • PISANY (Seal of the people of Pisa.)

From the circular matrix extends a hexagonal petaled central shaft pierced with two knobs between two sets of mouldings attached to the hexagonal flange of the counter-seal matrix. The counter-seal only bears the arms of the republic.
