As such, it appears on numerous official emblems in the United Kingdom, the former British Empire, and the Commonwealth realms.

[7] Henry V is the first English monarch to be depicted in heraldry wearing an imperial crown, and the first to be referred to as an emperor in his kingdom.

'[8][9] The crown is first described in an inventory made of Henry VIII's jewels in 1521:[6] 'Furste the kingis crowne of golde the Bordour garnisshed with Six Balacys[b] ffyve Saphures fyve pointed Diamoundys twanty Rubyes xix pearlys and iiij Collettis[c] the Balacys with the king And one of the crosses of the same Crowne garnisshed wt a greate Saphure an Emade Crased[d] iiij Balacys and ix pearlis not all of a sorte Item on the lefte side of the same Crosse a fflourre de luce set wt An ymage of Cryste with A greate Balace Brooken A less Balace A poynted dyamounde... 'Henry Rex[e] 'two pearlis and the Collet where a fayre Balace stode and A crampon[f] where the pearle stode.

[11] In the centre petals of the fleurs-de-lis were gold and enamel figurines of the Virgin Mary, St George and three images of Christ.

[14] According to an inventory drawn up for the sale of the king's goods, it weighed 7 lb 6 oz troy (2.8 kg).

[13] One of the royal figurines may have survived: a statuette of Henry VI matching the contemporary depiction of the crown was uncovered in 2017 by metal detectorist Kevin Duckett.

According to historian and Charles I biographer Leanda de Lisle, 'the crown was melted down on the orders of Oliver Cromwell but it is believed the figurine – which was one of several adorning the royal treasure – could already have been removed'.

[2] It was made by retired Crown Jeweller, Harry Collins, using 344 pearls and gemstones and employing authentic Tudor metalworking techniques.

[4] In 1876, Victoria was proclaimed Empress of India, and in 1880, the heraldic crown was altered to give it a more imperial form by making the arches semi-circular.

[4][5] The design of the crown and the new royal cypher was issued as a sealed pattern by the War Office rather than by the College of Arms.

[32][33][34] The coronet of the Prince of Wales created for the 1902 coronation[35] was heraldically represented similarly to the 1901 pattern crown, minus the central half-arch.

[21][37] Charles III adopted the Tudor Crown on his accession in 2022, similar to that last used under George VI but with some differences.

In the centre is a sapphire between two emeralds, and the outermost jewels are rubies, mirroring the heraldic St Edward's Crown of Elizabeth II.

[4] The 2023 design for use on police badges in the UK was a faithful reproduction of the crown selected by the King for the royal cypher but in a silver colour to match that of the Brunswick star.

[42] In Canada, a specifically Canadian design was unveiled which takes inspiration from the 2022 Tudor Crown but differs significantly in detailing and has been controversial.

[45] Use of the crowns for commercial purposes is specifically restricted in the UK (and in countries which are party to the Paris Convention) under sections 4 and 99 of the Trade Marks Act 1994, and their use is governed by the Lord Chamberlain's Office.

[46][47][48] It is also an offence under Section 12 of the Trade Descriptions Act 1968 to give a false indication that any goods or services are supplied to the monarch or any member of the royal family.
