Roman ring made in gold with a circular section ring, which widens towards the front to house in the centre a space in which a large orange carnelian stone is found. A carving can be seen on it that seems to represent the deity of a deity from the classical pantheon, although it is not possible to appreciate its exact attributes.

In the Roman Empire there was a great fondness for the ornamentation of stones, both carvings and cameos. The patrician families possessed large collections of these pieces, and after the fall of the empire the barbarians integrated them into their own treasures, passing them from generation to generation (mostly in the Germanic area) until the time of Charlemagne, the Holy Roman Empire, etc.
