The crown with which George I, King of Great Britain, was crowned on 20 October 1714. The cap is of crimson velvet or purple; welt of ermine; circle and arches of beaten gold. The ornaments are silver and set with diamonds; the larger stones are sapphires and emeralds, and a few small rubies. The balas in the cross in front was given to the crown by James II. The ball on which the upper cross is fixed is an aquamarine but the lower part is gold enamelled green. It is worn when the king goes to parliament, is made new for every coronation, and kept at the Tower of London.
