A £750,000 diamond ring, missing from the British Museum for six years, has only now been registered as lost.

The loss was revealed with the publication of museum's annual accounts where its cost has been written off.

A spokesperson said it was museum procedure to report losses five years after discovering a missing piece.

The ring was not on public display when it went missing, the museum said.
