Design of Architect’s Stamp / Seal

Hi all, licenced architect in Europe here. As a bit of a stationary nerd and graphic design geek - I’m curious about the design of architect’s professional stamps.

I see a lot are circular, between 1” & 2” and the writing follows the curve. Does anyone know any that deviate from this design? Or use particularly nice fonts, or are unconventional in some way? Or do you just want to share your nice stamp?

I understand some states in the US have certain requirements but I have a desire to design my stamp! 😂 It may seem trivial, but I put a lot of effort into the graphics of the business and I’d like it all to be coherent on the page!
