9th-11th century AD. Size 7, 5.0mm width with rounded face. All silver, not plated. Made with a core filling the inside which distributed the flowing silver and allowed for slower cooling. The core was then laboriously removed by hand and the inside of the ring polished. An imprint of the core is clear inside the ring. Silver and gold Viking rings are very rare, a small fraction of 1%. 1000 years old and suitable for modern wear! Gift boxed with certificate of authenticity.
