The BBC News website has this interesting report about the discovery at South Creake in Norfolk of a medieval ring decorated with the image of St George. It is being dated to the period 1350-1430. This is being linked to devotion to the saint in Norwich, a city with a major Guild of St George in the later middle ages, founded in 1385, and on which I have posted in part in English Iconoclasm II - the fate of the cult of St George.
The report, with pictures, can be seen at Rare medieval St George ring found in Norfolk
I see from the BBC webpages that a very similar ring found in Somerset was sold last month: the illustrated report about that example can be seen at St George medieval ring sold for £7,000 at auction
