London jewellers Wartski have donated the £57,395 necessary to purchase the 81 additional pieces of Anglo-Saxon treasure found last November in the same field as the 3,500-piece Staffordshire Hoard.

Geoffrey Munn, managing director of Wartski, said: "Both the chairman of Wartski, Nicholas Snowman, and I are thrilled to have a chance of securing the future of what can only be described as Staffordshire's Tutankhamun."

The most recent haul, which includes a helmet piece, a cross-shaped mount and an eagle-shaped mount, was discovered by a team from Archaeology Warwickshire. Stoke-on-Trent and Birmingham city councils jointly own the artefacts that have permanent displays in the West Midlands.
