Watch List notes:

ROMAN. Silver ring with carnelian intaglio. 2nd-3rd centuries AD. (25 mm). A solid silver ring with polygonal faces along arm ends in a large bezel mounted with a carnelian intaglio of an eagle with wings spread, head right, flanked by laurel branches; III in exergue. Toned, scratches on the silver. Carnelian intaglio is as made. Website shipping rates do not apply.

While the III in the exergue suggests a Legionary reference, nothing is explicitly stated on the ring to define that it is.
