An historic small jade seal measuring just over 3in long is set to sell for over £ 1million - despite its owner having no clue how much it was worth. The long-lost Imperial spinach-green seal is part of a European collection but its incredible history was only uncovered by experts from Bonhams auction house. They proved it was commissioned and handled by the legendary Chinese Emperor Qianlong himself during the late 18th century.
