Camilla, Duchess of Cornwall will wear a crown originally made for the Queen Mother for King George VI's coronation when Prince Charles becomes king.
The 74-year-old duchess was given Queen Elizabeth's blessing to take on the role of Queen Consort when her husband ascends the throne in a message over the weekend, and it's now been revealed that plans have already been drawn up for Charles' coronation day.
According to the Daily Mail newspaper, Camilla will wear a stunning crown featuring a platinum frame set with 2,800 diamonds - many of which came from Queen Victoria's Regal Circlet - and contains the controversial 105.6 carat Koh-i-Noor diamond.
The huge jewel was given as a gift to Victoria in 1856 by Sultan Abdulmedjid as a gesture of thanks for the support of Britain in the Crimean War, but many in India believe it is stolen and have demanded it back.
Queen Elizabeth, as she was known at the time, wore the crown at King George VI's coronation in 1937 and again without its arches to the state openings of parliament during her husband's reign, as well as to the current monarch's coronation in 1953.
It is currently on display with the Crown Jewels at the Tower of London.
Plans for Charles' coronation have been overhauled in recent years, with officials keen to make the ceremony "more streamlined" and up-to-date, so it is expected to have been shortened from the three-hour event that took place when his mother was crowned.
The ceremony will still be "spectacular" but has been redesigned to "better reflect the times", with more religious, ethnic, and cultural diversity.
In her message marking her Platinum Jubilee on Saturday, the queen said she hoped Camilla would be known as the Queen Consort, instead of the first-ever Princess Consort as had previously been intended.
She said: "I would like to express my thanks to you all for your support.
"I remain eternally grateful for, and humbled by, the loyalty and affection that you continue to give me. And when, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me; and it is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service."
And on Sunday, Charles said he was "deeply conscious of the honour" awarded by his mother.
