The Burkes give the royal blazon as follows:
Arms – Quarterly, first and fourth, gules, three lions passant guardant in pale or, for England; second, or, a lion rampant within a double tressure, flory, counterflory gules for Scotland; azure a harp or, stringed argent for Ireland; all surrounded by the Garter.
Crest – England – Upon the royal helmet, the imperial crown proper thereon a lion statant, guardant or, imperially crowned, also proper.
Supporters – Dexter, a lion rampant guardant or, crowned as the crest. Sinister, an unicorn argent armed, crined, and ungled or, gorged with a coronet composed of crosses pattée and fleurs-de-lis, a chain affixed thereto, passing between the forelegs, and reflexed over the back, also or.
Crest – Scotland – On an imperial crown proper a lion sejant affrontée gules imperially crowned or, holding in the dexter paw a sword, and in the sinister a sceptre erect, also proper.
Crest – Ireland – On a wreath, or and azure a castle, triple-towered, gold, a hart argent springing from the gate.
I’ve written out the abbreviations used – gu. into gules, pass. into passant, etc. but everything else is copied directly. I can’t quibble with the actual content of the blazon, although I would use a lot fewer commas. I’m also not sure why they give the blazons for the crests of Scotland and Ireland, but good to know, I guess.
The depictions of the royal arms are excellent examples of nineteenth-century heraldic art; whatever else I can say about the Burkes, they got some pretty good and period-typical heraldic artists. I’m planning on posting the rest of the complete achievements given for the royal family, as well as some of the labels, and possibly a few of the simple arms given for former monarchs.
