A chessman-style personal seal matrix of the medieval period. The seal has a sub-circular face and a tapering hexagonal-section handle. The handle is surmounted by three collars and a trefoil-shaped suspension loop. The engraved intaglio device is a religious scene within an ornately decorated quatrefoil border. The scene depicts the archangel Michael and the Virgin Mary. Saint Michael holds a shield and thrusts his spear into the mouth of the dragon at his feet. The Virgin Mary is crowned as Queen of Heaven, and holds the infant Jesus in her arms. The Latin inscription, in mixed Gothic and Roman style letters, reads S': WILL'I: DE: STINTESCOMBE, an abbreviated form that translates as 'Seal of William of Stintescombe'.

Stintescombe is the village in Gloucestershire now known as Stinchcombe. The name, in the form shown on the seal, is recorded circa 1155 in the Charters of Berkeley Castle. Its use illustrates the way in which locational surnames originated in England. In the 1911 census, for example, there are 540 instances of the Stinchcombe name.
