Following the Queen's passing, her eldest son and former Prince of Wales has taken on the title of King Charles III.
Although his coronation is yet to take place, the new King was formally proclaimed monarch at an Accession Council held on Saturday, September 10.
The ceremony was held at
and it was filmed for the first time as the Privy Council officially proclaimed His Majesty as King Charles III with Camilla, Queen Consort and William, Prince of Wales present.
King Charles' official coronation will take a lot of preparation and it could take around 12 months for the grand ceremony to take place.
But which crown will King Charles III wear at his coronation and has he inherited the Crown Jewels following the death of Queen Elizabeth II?
What crown will King Charles III wear at his coronation?
King Charles III will wear the St Edward's Crown when he is officially declared as the King during his coronation.
The crown, which is only used during coronation ceremonies, was made in 1661 and initially belonged to Edward the Confessor.
The coronation crown is remarkably heavy, made of solid gold and typically resides at the Tower of London between state events as part of the Crown Jewels collection.
Queen Elizabeth II revealed in 2018 that she had the crown resized ahead of her coronation.
She said in an interview with the BBC : "You see, it's much smaller isn't it? "It would have been up to about there when my father wore it."
It is expected that the crown will be resized once more for the coronation of King Charles III.
What is the value of the St Edward's Crown?
The glorious crown bares 2,868 diamonds, 17 sapphires, 11 emeralds, four rubies and 269 pearls.
Although the exact value of the St Edward's Crown has been heavily debated over the years, experts have speculated that it is worth between £3bn and £5bn.
The St Edward’s Crown features on royal cyphers and the Royal Mail logo is also based on the coronation crown.
Will King Charles III inherit the Crown Jewels?
King Charles III will inherit all crown jewels following the death of Her Majesty The Queen as the royal jewellery and regalia belongs to the monarch and the Crown as an institution.
The King will use the Imperial State Crown, which has recently been placed on the Queen's coffin for the Lying-In-State and her State funeral, for ceremonial occasions including the opening of parliament.
