The Coronation Crown of George IV is an elaborate coronation crown made specially for King George IV in 1821. At 40 cm (16 in) tall and decorated with 12,314 diamonds, it was said to make him look like a "gorgeous bird of the east". The innovative gold and silver frame, created by Philip Liebart of Rundell, Bridge & Rundell, had been designed to be almost invisible underneath the diamonds. A plan to remove the traditional fleurs-de-lis and introduce the rose, thistle and shamrock, the floral emblems of England, Scotland and Ireland, was abandoned following objections by the College of Heralds. As a general rule, the maintenance caps in British crowns are made of crimson or purple velvet, but this crown differed in having a dark blue cap.
