Coronet (Lat. corona, a crowm), a crown worn by princes and noblemen. It was not known in England prior to the reign of Henry III., and the oldest remaining representation of one is on the monument of John of Eltham, second son of Edward III., who died in 1334. All the coronets at present worn by the British nobility surround caps of crimson velvet edged with ermine. That of the prince of Wales was anciently a circle of gold, with four.crosses pattee on the edge between as many fleurs de lis; but since the restoration it has been closed with one arch, adorned with pearls, and surmounted by a mound and cross. That of a duke is enriched with precious stones and pearls, and adorned with eight large strawberry leaves. That of a marquis is set round with four strawberry leaves interposed between as many pearls. That of an earl has eight pearls alternate with as many strawberry leaves, but set on pyramidal points much above them. That of a viscount is surrounded only by an indefinite number of pearls. The baron's coronet, which was first granted by Charles II., has six pearls set around it at equal distances. In England coronets are worn at the time of a coronation by peers and peeresses.
On the continent of Europe coronets are not worn, but are merely represented with other heraldic insignia.
