Camilla is set to receive the Queen Mother's priceless 1937 crown when Charles becomes king, it has been reported.
The Queen Mother’s crown, which was created for King George VI’s coronation in 1937, features 2,800 diamonds and was given to Queen Victoria in 1856 by the Sultan of Turkey as a gesture of gratitude for British support during the Crimean War.
The crown also famously features the 105-carat Koh-i-Noor diamond, which originated in India, in a platinum mount.
Camilla will be given the crown when Charles accedes to the throne as part of her role as Queen Consort, something which was announced by the Queen over the weekend, the Daily Mail reported.
In response to Her Majesty's historic announcement, Charles issued his own statement stating his sheer gratitude to his mother for her support, adding: 'We are deeply conscious of the honour represented by my mother’s wish.'
He also payed tribute to the Queen's Platinum Jubilee this year, by saying her ‘devotion to the welfare of all her people inspires still greater admiration with each passing year’.
It is thought the Queen actually gave her permission for Charles to refer to his wife as 'Queen Camilla' in his coronation vows many years ago.
He reportedly changed his coronation vows to include his wife’s title as part of an update to plans for the Westminster Abbey ceremony five years ago, a senior palace source said.
The source explained: ‘This is something that has been on the Prince of Wales’ mind for some time, but the timing had to be right. There was a nervousness, they wanted to get it right.
‘It’s been a done deal for some time, but the question has been how best to execute it. You are not going to please everyone.'
Another senior royal source reportedly said the Queen felt Camilla ‘deserved’ to get the proper title that ‘comes with the job’.
They said the Duchess has never tried to 'overshadow' and always played a 'supportive role' but she has also 'carved a role out for herself'.
Other changes to the coronation plans have also been made, with officials reportedly shortening it from usual three-hour long event to ‘better reflect the times’ and it will be more reflective of religious, cultural and ethnic diversities.
