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.
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
the circlet of the Royal Crown. This coronet was also assigned in the warrant of 9th February, 13 Charles II.
It will be observed by those who compare one heraldic book with another that I have quoted these rules differently from any other work upon the subject. A moment's thought, however, must convince any one of the accuracy of my version. It is a cardinal rule of armory that save for the single circumstance of attainder no man's armorial insignia shall be degraded. Whilst any man's status may be increased, it cannot be lessened. Most heraldic books quote the coronet of crosses-patée, fleurs-de-lis, and strawberry leaves as the coronet of the "grandsons" of the sovereign, whilst the coronet of crosses-patée and strawberry leaves is stated to be the coronet of "nephews" or cousins of the sovereign. Such a state of affairs would be intolerable, because it would mean the liability at any moment to be degraded to the use of a less honourable coronet. Take, for example, the case of Prince Arthur of Connaught. During the lifetime of Queen Victoria, as a grandson of the sovereign he would be entitled to the former, whereas as soon as King Edward ascended the throne he would have been forced to relinquish it in favour of the more remote form.
The real truth is that the members of the Royal Family do not inherit these coronets as a matter of course. They technically and in fact have no coronets until these have been assigned by Royal Warrant with the arms. When such warrants are issued, the coronets assigned have up to the present time conformed to the above rules. I am not sure that the "rules" now exist in any more potent form than that up to the present time those particular patterns happen to have been assigned in the circumstances stated. But the warrants (though they contain no hereditary limitation) certainly contain no clause limiting their operation to the lifetime of the then sovereign, which they certainly would do if the coronet only existed whilst the particular relationship continued.
The terms "grandson of the sovereign" and "nephew of the sovereign," which are usually employed, are not correct. The coronets only apply to the children of princes. The children of princesses, who are undoubtedly included in the terms "grandson" and "nephew," are not technically members of the Royal Family, nor do they inherit either rank or coronet from their mothers.
