Crown jewels

Crown Jewels are the objects of metalwork and jewellery in the regalia of a current or former monarchy. They are often used for the coronation of a monarch and a few other ceremonial occasions. A monarch may often be shown wearing them in portraits, as they symbolize the power and continuity of the monarchy. Additions to them may be made, but since medieval times the existing items are typically passed down unchanged as they symbolize the continuity of the monarchy.
Crown (headgear)

A crown is a traditional symbolic form of headwear, not hat, worn by a monarch or by a deity, for whom the crown traditionally represents power, legitimacy, victory, triumph, honor, and glory, as well as immortality, righteousness, and resurrection. In art, the crown may be shown being offered to those on Earth by angels. Apart from the traditional form, crowns also may be in the form of a wreath and be made of flowers, oak leaves, or thorns and be worn by others, representing what the coronation part aims to symbolize with the specific crown. In religious art, a crown of stars is used similarly to a halo. Crowns worn by rulers often contain jewels.

Coronation of the British monarch

The coronation of the British monarch is a ceremony in which the monarch of the United Kingdom is formally invested with regalia and crowned at Westminster Abbey. It corresponds to the coronations that formerly took place in other European monarchies, all of which have abandoned coronations in favour of inauguration or enthronement ceremonies.
Coronation Chair

The Coronation Chair, known historically as St Edward's Chair or King Edward's Chair, is an ancient wooden chair on which British monarchs sit when they are invested with regalia and crowned at their coronations. It was commissioned in 1296 by King Edward I to contain the coronation stone of Scotland—known as the Stone of Destiny—which had been captured from the Scots who kept it at Scone Abbey. The chair was named after Edward the Confessor, and was previously kept in his shrine at Westminster Abbey.
Danish Crown Regalia

Danish Crown Regalia are the symbols of the Danish monarchy. They consist of three crowns, a Sceptre, Globus cruciger, the Sword of state and an Ampulla . The Danish Royal Regalia are kept in the treasury at Rosenborg Castle. The oldest of these is Christian III's sword of state from 1551. They further include King Christian IV's diamond; pearl- and gold-embroidered saddles; objects carved from ivory and rock-crystal; lapidary pieces of precious stones, and brooches in the form of fantastic animals.
Regalia of Norway

Remade in its current form for King James V of Scotland in 1540, the crown is part of the Honours of Scotland, the oldest surviving set of Crown jewels in the United Kingdom.

Coronation of Elizabeth II
The coronation of Elizabeth II took place on 2 June 1953 at Westminster Abbey, London. Elizabeth II ascended the throne at the age of 25 upon the death of her father, George VI, on 6 February 1952, being proclaimed queen by her privy and executive councils shortly afterwards. The coronation was held more than one year later because of the tradition of allowing an appropriate length of time to pass after a monarch dies before holding such festivals. It also gave the planning committees adequate time to make preparations for the ceremony. During the service, Elizabeth took an oath, was anointed with holy oil, invested with robes and regalia, and crowned Queen of the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon.
Coronations in Europe

Coronations in Europe were previously held in the monarchies of Europe. The United Kingdom is the only monarchy in Europe that still practices coronation. Current European monarchies have either replaced coronations with simpler ceremonies to mark an accession or have never practiced coronations. Most monarchies today only require a simple oath to be taken in the presence of the country's legislature.
