New York's Mamdani calls on King Charles to 'return' Koh-i-Noor diamond taken from India

New York Mayor Zohran Mamdani on Wednesday called on King Charles III to "return" the Koh-i-Noor diamond, a 105.6 carat gem that was mined in India and is now the star of Britain's crown jewels. The diamond has been in British hands since 1849 but its ownership is contested with several countries laying claim.
