The main diamond in the crown, cut from the largest ever found, 3,106 carats
The Crown of the British Crown on the coffin of Queen Elizabeth II is a powerful symbol of wealth, majesty and royal sovereignty.
The crown, resting on a purple cushion, was decorated with 2,686 diamonds, 269 pearls, 17 sapphires and 11 emeralds, which sparkled as the coffin traveled from Buckingham Palace to the Great Hall in Westminster Abbey, where it rests on a raised plinth. .

The coffin was escorted by soldiers in scarlet ceremonial uniforms.

The crown was commissioned for the coronation of Elizabeth's father, King George VI in 1937, and she wore it to her own coronation in 1953 and was immortalized in a famous portrait.
The crown is also worn during the annual ceremony to mark the commencement of Parliament and is kept with other precious jewels in the famous Tower of London.
The second royal crown, St. Edward, was made in 1661 from pure gold for the coronation of King Charles II.
It is used exclusively at the time of coronation because it is too heavy to carry. It weighs two kilograms, twice as much as the crown of the royal state.
Too heavy to hold
Once the queen joked that the crown was too heavy and that if you look down, "your neck might snap".
"Fortunately, my father and I had such a shaped head that once you put it on it doesn't move," Elizabeth II told the BBC in 2018.
Due to weight, she stopped wearing the crown at the beginning of the proceedings of the parliament when she entered her 90th year of life. Instead, the crown was placed on a pillow.

The main diamond on the front is called Cullinan II. It was cut from the largest diamond ever found in South Africa in 1905. It was found at the Premier mine in Cullinan, South Africa and weighs 3106 carats (621 grams).

The Cullinan was divided into nine large and very small cut diamonds. The largest cut diamond is called the Great Star of Africa (Cullinan I) and is 530 carats (106 grams). It sits atop the English royal scepter.

The second largest part (Cullinan II) is in the English royal crown. Both of these objects are kept as part of the English royal jewels in the Tower of London.
Other impressive crown jewels include the Black Prince's Ruby and the Stuart Sapphire.
