The Story

The Koh-i-Noor is a 105.6 carat colorless diamond cut as an oval brilliant. It is set in the Crown of Queen Elizabeth The Queen Mother, made for the 1937 coronation, and is on public display in the Jewel House at the Tower of London.

The stone's early history is heavily mythologized, and centuries of legend have attached it to rulers it cannot be tied to. The first verifiable record dates from the 1740s, when the historian Muhammad Kazim Marvi documented the diamond on the Mughal Peacock Throne, which Nader Shah of Iran had looted from Delhi in 1739. After Nader Shah's assassination in 1747 the stone passed to Ahmad Shah Durrani of Afghanistan, and in 1813 to Maharaja Ranjit Singh of the Sikh Empire in Punjab.

Following the Second Anglo-Sikh War, the 1849 Treaty of Lahore ceded the diamond to Queen Victoria. The transfer remains contested: Maharaja Duleep Singh was a ten year old child at the time, and the governments of India, Pakistan, Iran and Afghanistan have all claimed the stone since 1947. The British government maintains the 1849 treaty made the transfer legal. In 1852 Prince Albert had the diamond recut from about 186 old carats (some sources give 191) to its present 105.6 carats to improve its brilliance.

1849

Treaty of Lahore cedes the diamond to Britain

After the Second Anglo-Sikh War, the treaty compelled ten year old Maharaja Duleep Singh to surrender the diamond to Queen Victoria along with the Punjab. The legality of the transfer is still disputed.

1852

Recut in London

Prince Albert commissioned a recut by Garrard of London, reducing the stone from about 186 old carats to 105.6 carats over 38 days at a cost of 8,000 pounds.

Curse legend on male owners
