FREETOWN (Reuters) - A Christian pastor has found one of the world's largest uncut diamonds - weighing 706 carats -- in Sierra Leone's eastern Kono region.

The stone, a photograph of which was posted on the president's official website, is being stored in the country's central bank, government sources said.
