Experts debate age of York sapphire ring

A group of experts convened recently at the Yorkshire Museum to debate the age of the beautiful Escrick Ring, found in a field near York, England. The ring was believed to date from the 12th through 16th centuries, but some now think as early as the 5th century. (photo)

The gold, glass and sapphire ring, discovered in 2009 near the village of Esrick, has stumped the archaeology community, causing Yorkshire Museum curator of archaeology, Natalie McCaul, to invite 30 experts to evaluate the artifact. Further high-tech research will take place at Durham University.
