The coronet of the Prince of Wales is exactly like the official (St. Edward's) crown, except that instead of two intersecting arches it has only one. An illustration of this is given in Fig. 646 (this being the usual form in which it is heraldically depicted). It should be noticed, however, that this coronet belongs to the prince as eldest son of the Sovereign and heir-apparent to the Throne, and not as Prince of Wales. It was assigned by Royal Warrant 9th February, 13 Charles II. The coronet of the Princess of Wales, as such, is heraldically the same as that of her husband. [Illustration: FIG. 647.--Coronet of the younger children of the Sovereign.] The coronets of the sons and daughters or brothers and sisters of a sovereign of Great Britain (other than a Prince of Wales) is as in Fig. 647, that is, the circlet being identical with that of the Royal Crown, and of the Prince of Wales' coronet, but without the arch. This was also assigned in the warrant of 9th February, 13 Charles II. Officially this coronet is described as being composed of crosses-patée and fleurs-de-lis alternately. The grandchildren of a sovereign being sons and daughters of the Prince of Wales, or of other sons of the sovereign, have a coronet in which strawberry leaves are substituted for the two outer crosses-patée appearing at the edges of the coronet, which is officially described as composed of crosses-patée, fleurs-de-lis, and strawberry leaves. Princes of the English Royal Family, being sons of younger sons of a sovereign, or else nephews of a sovereign being sons of brothers of a sovereign, and having the rank and title of a duke of the United Kingdom, have a coronet composed alternately of crosses-patée and strawberry leaves, the latter taking the place of the fleurs-de-lis upon {364} the circlet of the Royal Crown. This coronet was also assigned in the warrant of 9th February, 13 Charles II.
