A little-known crown that was last worn nearly 200 years ago could be the solution to the Koh-i-Noor diamond controversy.

In fact, the fear is growing in these hours that an international quarrel could be triggered on the occasion of the coronation of King Charles III: that day, Camilla is expected to wear the crown with the famous diamond, donated to Queen Victoria by the last Sikh emperor of India, which was only 10 years old at the time.

India claims ownership, but it is not the only country that would like to have the precious and unique gem back.

There is a choir between Pakistan, Bangladesh and Afghanistan. 

In particular, the ruling party of Indian Prime Minister Narendra Modi would have expressed concern: the hypothesis that Camilla wears it, already rekindles the memory of British colonialism.

The Queen Mother's crown with the Koh-i-noor diamond

But Buckingham Palace is said to be considering the use of other crowns, including the one worn by Queen Adelaide at the coronation of her husband, William IV, in 1831.

Other options would include the 1820 Diamond Diadem, used for George IV's coronation and worn by the late Queen Elizabeth II, on her way to her coronation in 1953, and at each annual Parliament opening.

The crowns created for the coronation of Queen Alexandra - the wife of King Edward VII - and King George V's wife, Queen Mary, are other options under consideration, the Telegraph reported.

Other options: replacing the Koh-i-Noor with a crystal replica or simply removing the diamond.
