Prince William of Wales, as second in line to the throne, uses a white label of three points like his father, but has in addition a small red ‘escallop’ or sea-shell on the central point. 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.

On the granting of arms to Prince Harry in September 2002, Garter said, “After changing convention for Prince William by using symbols derived from his maternal arms it made sense to develop this further for Prince Harry. This is especially significant because, unlike his elder brother who will one day see his arms alter to reflect his changing responsibilities, Prince Harry will always keep the escallop shells from his mother’s Spencer family arms and, in time, may pass them on to his children. I understand that both Princes are delighted to bear Arms that celebrate both their parents’ families and it has been a pleasure to evolve the rules of Royal Heraldry in order to make this possible.”

Princes William and Harry also display the coronet of their 'degree', as a Sovereign's grandchild, which has two 'crosses formy' and two strawberry leaves alternating with four fleurs-de-lys.
