The Koh-i-Noor diamond controversy surrounding Camilla's coronation crown.

The Koh-i-noor diamond, a 105-carat gemstone with a history of curses and conquests, will not be worn by Camilla, the queen consort, at King Charles III's coronation. The diamond has become a focus of anti-colonial anger, with India and other nearby countries demanding its return. Legend has it that only women, especially queen consorts, can wear the diamond safely. The British royal family has no intention of parting with the gemstone, which is kept on display in the Tower of London.
