Based on the design of Queen Victoria's Crown of 1838, which had fallen into disrepair, it was made in 1937 for the coronation of King George VI.

[5] The Tudor Crown had more pearls and jewels than its medieval predecessor, and the centre petals of each of the fleurs-de-lis had images of Christ, the Virgin Mary, and St George.

[7][8] Following the abolition of the monarchy and the execution of Charles I in 1649, the Tudor Crown was broken up by order of Oliver Cromwell during the Interregnum,[9] and its valuable components were sold for £1,100.

Made by Rundell and Bridge using old and new jewels, it had a crimson velvet cap with ermine border and a lining of white silk.

It weighed 39.25 troy ounces (43.06 oz; 1,221 g) and was decorated with 1,363 brilliant-cut, 1,273 rose-cut and 147 table-cut diamonds, 277 pearls, 17 sapphires (including St Edward's Sapphire, thought to have been taken from the Confessor's ring when his body was reinterred at Westminster Abbey in 1163), 11 emeralds, 4 rubies, and the Black Prince's Ruby (a cabochon red spinel).

[13] At the State Opening of Parliament in 1845, the Duke of Argyll was carrying the crown before Queen Victoria when it fell off the cushion and broke.

[17] A faithful copy of the 1838 crown, which had fallen into a poor state of repair, was made in 1937 by the jewellers Garrard & Co. for George VI.
