Buckingham Palace has announced that Queen Consort Camilla will not wear the Koh-i-Noor diamond during the coronation of King Charles III in May. Instead, she will modify Queen Mary's crown using diamonds from Queen Elizabeth II's personal collection, in order to avoid the controversy surrounding the gem. This will be the first time in history a crown will be "recycled" for a coronation, as the coronation of King Charles III is set to take place in May.
