The medieval gold finger ring found at Waitby, near Kirkby Stephen, was found by a metal detectorist in a well-preserved condition.
The small, plain band is decorated with a stepped and bevelled rectangular gold bezel mounted with a purple stone, possibly amethyst.
It is known to be dated from some time within the 13th and 14th centuries, the inquest heard.
Commenting on the ring in the artefact’s notes, archaeologist Dr Dot Boughton wrote: “Similar medieval gold rings are recorded on the database, for example from Tolleshunt Major in Essex, Kexby in North Yorkshire and Chester.
“They are all dated from the 13th or early 14th century and were submitted for consideration as treasure.”
The ring was found by Richard Hunter, a metal detectorist from Peterlee, on August 17 last year.
He was metal detecting on land owned by Mrs GM Hewetson.
As the ring was found to contain 10 per cent precious metal, it qualified as treasure under the 1996 Treasure Act.
