Koh-i-Noor: The History of the World's Most Infamous Diamond is a 2017 book on the Koh-i-Noor diamond written by William Dalrymple and Anita Anand. The gem is one of the largest cut diamonds in the world, weighing , and part of the British Crown Jewels. Koh-i-Noor is Persian for "Mountain of Light"; it has been known by this name since the 18th century. It was originally mined in South India (in the present-day state of Andhra Pradesh) long before the 13th Century CE, and changed hands between various factions in modern-day India, Pakistan, Iran, and Afghanistan, until being ceded to Queen Victoria after the Second Anglo-Sikh War, which resulted in the Punjab region falling under Company rule in 1849. Summary Introduction The introduction of the book describes the event at the center of contemporary controversy, which is that the East India Company compelled 10-year-old Duleep Singh, heir to the Sikh Empire, to agree to the 1849 Treaty of Lahore, and its stipulation that he give the Koh-i-Noor to the East India Company. Shortly after the diamond came into the possession of the East India Company, Governor-General Lord Dalhousie tasked 22-year old civil servant Theo Metcalfe with compiling the history of the diamond prior to 1849. Metcalfe himself said that he was unable to do a good job, but what he wrote has become the most popular and circulated record of the diamond's history. The Jewel in the Throne Indian Prehistory of the Koh-i-Noor The chapter discusses how India and the rest of the world thought about diamonds before around 1500. Before the 1725 discovery of diamond mines in Brazil, almost all of the world's diamonds came from the Indian subcontinent. Various classical Hindu texts, including the Garuda Purana, Bhagavad Gita, Vishnu Purana, the Ratna Shastra, all talk about diamonds and people's relationship to them. There are Indian cultural traditions to depict jewelry in the arts. There is a summary of the chapter on diamonds in Garcia de Orta's 1563 book Colóquios dos simples e drogas da India. The Mughals and the Koh-i-Noor The chapter begins with the story of Babur establishing the Mughal Empire in India. In his autobiography, Baburnama, he discusses his jewels including large diamonds. There are various accounts of Mughal jewels including reports sent by English ambassador Thomas Roe from the Mughal court to England, Jahangir's autobiography, Tuzk-e-Jahangiri, and the Shahjahannama.
