Marvi writes: An octagon, shaped like a European hat, with circular brim, had its sides and canopy gilded and studded with jewels. On top of this was placed a peacock made of emeralds and rubies; onto its head was attached a diamond the size of a hen’s egg, known as the Koh-i-Noor – the Mountain of Light, whose price no-one but God Himself could know! The wings were studded with jewels; many pearls, each the size of a pigeon’s egg, were strung on wire and attached to the pillars supporting the throne.
