Prince Henry of Wales (or, as he is usually known, Prince Harry)
uses, like all grandchildren of the monarch except his elder brother, a
five-pointed label. In his case this is ‘charged’, or marked, with red escallops
on the first, third and fifth points. When, in due course,
Prince Harry becomes the son or brother of the monarch, his label will be
reduced to three points. In that event, the two blank points will
disappear, leaving three, each of them charged with a red escallop. Shamus Toomey, 26 September 2002

which includes full colour renditions of the arms of Prince Henry, his brother
Prince William and his mother the late, Diana, Princess of Wales. Graham Bartram, 9 October 2000
