The letters around the shield are a form of uncials, which followed the Roman square capitals from the 5th to the 13th century. The letter S' is an abreviation for the latin word Sigillum. The christian names have been latinised too. The escutcheon rests upon a bed of crosses in a romanesque or norman style. The artist was inspired by a 13th century seal.   

Based on a drawing like this one a jeweller can engrave the heraldic arms by hand or using laser on a signet ring in gold or on a stone mounted in a frame of gold. An escutcheon could alternatively be engraved on a necklace of gold or silver. To have one's heraldic arms engraved on to a seal of bronze is an ancient tradition. In olden days it was a proof of identity when important documents were signed by one's signature (if one could write, which wasn't always the case) together with an imprint of one's heraldic bearings or escutcheon in wax.
