"It is a bit of a mystery why something from the continent at that time should turn up in the middle of the Leicestershire countryside," said Peter.
Adding that it dated back to around the time when there may have been a Viking settlement in that area, he said "You do wonder if we might be looking at something from a hairy Viking hand!"
The third ring was found in Waltham on the Wolds and comes from the later medieval period, but is equally mysterious and, with an unusual iron setting, seems to have its own story to tell.
"It could have belonged to somebody who'd made their money from iron and wished to demonstrate that, or there is something more ritualistic about it," said Peter. "It could be that it's to do with witchcraft, maybe a sort of magic, ritual significance to ward off evil spirits."
It is hoped that in time all three items will join larger collections in the region's museums. Both finger rings have already been earmarked for Melton Carnegie Museum.
