Lars it may well be from England, contain some silver and feature a Greco-Roman god on the bezel - whatever. But it is certainly not Roman. The octagonal bezel of stepped design indicates a likely origin roughly between the 15th and 18th century. Hard to be certain from a photograph because this design remained in circulation for centuries in Europe. A number of stylistically similar examples are featured in the 'Ralph Harari Collection of Finger Rings" by John Boardman & Diana Scarisbrick. The greenish patina on the underside betrays a predominantly copper alloy. Classical gods/goddesses never went out of fashion, and continued to appear throughout the late medieval, Renaissance and "Neoclassical periods.
