Mamdani says he would ask King Charles to return Koh-i-Noor

Zohran Mamdani brought one of the world’s most contested diamonds into the orbit of elected politics in New York City on Wednesday, saying he would have urged King Charles III to return the Koh-i-Noor to India if the two had spoken privately.

The comment came before Mamdani joined the king for a 9/11 memorial wreath-laying in Lower Manhattan during Charles’s U.S. visit. Mamdani and Charles did not meet in private, and no private exchange was reported later in the day, but the mayor’s remark underscored how a dispute once driven largely by historians, activists and museums has become a live question for public officials.

The Koh-i-Noor is commonly described as a 105.6-carat diamond now set in the Crown of Queen Elizabeth the Queen Mother at the Tower of London, as part of the British Crown Jewels. It is widely believed to have originated in India, with one commonly cited source being the Kollur mine in present-day Andhra Pradesh. The stone was given to Queen Victoria in 1849 under the Treaty of Lahore after the First Anglo-Sikh War, a transfer that has made it a lasting symbol of imperial extraction.

India has long claimed the diamond and has previously asked Britain to return it. Pakistan, Afghanistan and Iran have also staked claims to the stone, adding to the diplomatic complexity around any effort to repatriate it. Britain’s government has maintained that the Koh-i-Noor was obtained legally under treaty terms and has rejected return demands.

The issue remains politically active. In 2023, The Telegraph reported that India was preparing a diplomatic campaign to reclaim the Koh-i-Noor and thousands of other artifacts from Britain, a sign that restitution claims have moved beyond symbolic grievance and into the language of statecraft. That makes Mamdani’s intervention notable not just for its subject, but for its setting: a New York mayor speaking about imperial plunder in the presence of the British monarch.

Whether any practical pathway exists for the diamond to leave the Tower of London remains uncertain. The British government has shown no willingness to reverse its position, and the stone’s status in the Crown Jewels gives it both legal and symbolic weight. But Mamdani’s comment made clear that the call for restitution is no longer confined to museum galleries and activist campaigns. It is now entering the political mainstream, where elected officials are increasingly willing to say publicly that imperial objects should go home.
