Late 9th-early 11th century AD. Gilt bronze, size 5 1/4. Medium width band 3.mm, with a rounded face. The inside with distinct tool marks from a removal of the central core after casting. That process was very labor intense, but assured that the molten metal spread and cooled evenly. Professionally refurbished with the 24 karat gold overlay restored. Gift boxed with a certificate of authenticity.
