Hi, Aaron, and congratulations on becoming an armiger.
When considering a signet, remember that it is small, so to be effective it should show a small part of the achievement, not the whole.
That small part can be the crest, or (if it is not too detailed) the shield (as Robert Amyot has) – or, if you have a badge as part of your grant, that could be used instead.
It should be in reverse, and engraved, so that when impressed in wax it is “proud” and faces in the right (that is, dexter) direction.
(As an armiger you no doubt know that left and right on a shield are given as from behind the shield, so that dexter is the apparent left, and sinister the apparent right.)
I look forward to seeing an illustration of the arms and, in due course, the signet as well.
Again, congratulations.
Regards,
Mike
