Nader sent forth 1,000 cavalrymen to each district of the city to ensure the collection of taxes. But perhaps the greatest riches were plundered from the treasuries of the Mughal dynasty's capital. The Peacock Throne was also taken away by the Persian army, and thereafter served as a symbol of Persian imperial might. Among a trove of other fabulous jewels, Nader also gained the Koh-i-Noor ("Mountain of Light") and Darya-ye Noor ("Sea of Light") diamonds. It is estimated that the total worth of the treasures plundered came to perhaps 700 million rupees. This was roughly the equivalent to £90 million sterling at the time, or £8.2 billion sterling in the early 21st century.
