The Curse of the Koh-i-Noor Diamond

The Koh-i-noor diamond has a long, storied history -- and a reputation for bringing trouble to its (male) owners. In this episode, Katie and Sarah trace the adventures of the infamous diamond, from its Indian origins to its final resting place in Britain.

Topics Discussed

Episode Summary

Executive Summary: The episode recounts the Koh-i-Noor diamond’s long, turbulent history from its likely origin in India to its seizure by the British, emphasizing how the stone repeatedly changed hands through conquest, diplomacy, betrayal, and dynastic conflict. The hosts frame it as a symbol of power, curse, and colonial theft, while also tying in the tragic displacement of Duleep Singh and his mother Rani Jindan Kaur.

Main Topics: Origins and early prestige of the Koh-i-Noor (Priority: 5/5): The diamond likely came from India’s Krishna River region and appears in records by the late 1200s, where it was already valued as an extraordinary, politically significant treasure. The diamond as a political instrument (Priority: 5/5): Across Mughal, Persian, Afghan, and Sikh rule, the stone is repeatedly used as tribute, diplomatic leverage, and a marker of legitimacy rather than mere jewelry. Nadir Shah and the naming of the stone (Priority: 5/5): The diamond is famously discovered hidden in a turban exchange, prompting Nadir Shah to name it Koh-i-Noor, or 'Mountain of Light,' after realizing its enormous value. Violence, betrayal, and the 'curse' motif (Priority: 4/5): The transcript repeatedly links the diamond to misfortune—madness, assassinations, coups, and family conflict—supporting the folklore that possession brings disaster. Ranjit Singh, Duleep Singh, and the Sikh empire’s collapse (Priority: 5/5): The diamond passes to Ranjit Singh and then to the child ruler Duleep Singh, whose defeat in the Anglo-Sikh wars leads to the British seizure of the stone and his forced removal. British possession and colonial controversy (Priority: 5/5): The Koh-i-Noor is recut, placed among the Crown Jewels, and displayed publicly, but its acquisition is described as dubious because it was taken from a child ruler under colonial pressure. Rani Jindan Kaur and the emotional aftermath (Priority: 4/5): Duleep Singh’s mother becomes a lasting symbol of Sikh resistance and exile, and the episode uses her story to underscore the human cost of empire and the diamond’s legacy.

Key Arguments: The Koh-i-Noor’s importance came from political power and symbolism, not just rarity or beauty, as rulers used it to legitimize rule and negotiate alliances. The stone’s history is inseparable from violence: succession struggles, invasions, coups, and colonial conquest repeatedly follow its movement. British ownership is presented as morally questionable because the diamond was taken from Duleep Singh, an 11-year-old deposed ruler. The diamond’s recutting into a smaller, symmetrical crown jewel is framed as a loss of its original grandeur and cultural identity. The story of the diamond mirrors broader histories of empire, extraction, and contested heritage claims, which is why modern calls for repatriation continue. Rani Jindan Kaur and Duleep Singh show that the diamond’s legacy is also personal and political, shaping identity, exile, and resistance long after the stone changed hands.

Data Points: Original size: 191 carats - The Koh-i-Noor in its earlier, unreduced form was described as 191 carats. Early historical reference: Late 1200s - The first dated reference to a possible Koh-i-Noor appears during Alauddin Khalji’s invasion of the Deccan plateau. Valuation under Khalji: Half the daily expense of the whole world - A historical account describes the diamond as extraordinarily valuable after its capture. Value under Humayun: Expenditure of the whole universe for two and a half days - The transcript notes a later dramatic increase in its estimated worth during exile and diplomacy. Year recut by the British: 1852 - The diamond was cut down and reshaped after falling into British hands. Size after recutting: 81 carats - Its British-era form was reduced to a much smaller crown-jewel stone. First Anglo-Sikh War: 1845-1846 - This war weakened Duleep Singh’s kingdom and marked the start of British domination of Punjab. Second Anglo-Sikh War: 1848-1849 - This conflict ended with the complete loss of Sikh control and the surrender of the Koh-i-Noor. Age of Duleep Singh when made Maharaja: Just after his sixth birthday - He became ruler as a child with his mother acting as regent. Age of Duleep Singh when forced to sign away the diamond: 11 - The British compelled the boy Maharaja to surrender title, property, and the Koh-i-Noor. Ranjit Singh’s army: 600 horsemen - Ranjit Singh arrived with this force to claim the diamond after Shah Shujah delayed payment. Time apart from mother: 13 years - Duleep Singh reunited with Rani Jindan Kaur after a long separation caused by imprisonment and exile.

Pivotal Quotes: "Kohi Noor, or Mountain of Light" — Narrator: Nadir Shah names the diamond after discovering it hidden in the turban exchange. "they took the diamond from a kid. Candy from a baby." — Host: The hosts underscore the colonial injustice of British acquisition. "a poor woman whose ashes have been squabbled over" — Charles Dickens: Quoted to reflect the contested legacy of Rani Jindan Kaur and the politics surrounding her remains.

Implications: The episode frames the Koh-i-Noor as a case study in cultural plunder and contested heritage, reinforcing modern arguments for repatriation and showing how relics can embody empire, identity, and historical injustice.
