Emperor Shah Jahaan's royal seat stood in Diwan-i-Khas (Hall of Private Audience), made of solid gold frame and studded with precious stones such as rubies, emeralds, pearls and diamonds including the world's largest, the Kohinoor.
It was pilfered by Nadir Shah, the ‘Persian Napoleon'. After passing several hands, it is now part of England's royal Crown Jewels collection.
