What do you call the decorative metal on the stem and shank?

[uneek]

I know there are proper names for each part of a pipe. I wanted to know what to call the embedded emblems, like on the stem of a GBD. Also, what do you call the silver or brass ring that goes around the shank at the mortise hole. I've read different things and wanted to get the scoop from you guys.
Thank you,

Band.
BTW, don't think I've ever seen one on the stem; shank only. Sometimes for repair, often for decoration and strength.

Do the terms Rondell and Roulette have any roll here? I was thinking one was the embedded emblem and the other a fancy name for the band but which would be which?

Ferule, maybe?

Band, ferrule, olive for a military mount, spigot cap for a spigot mount, but for a simple band of silver, nickel, gold, or whatever, that covers the end of the shank where it meets the stem, it's called a band.

The small metal GBD emblem on a stem is called a rondelle.

Thanks Sablebrush and ashdgger, that is precisely what I wanted to verify.
All you guys are tremendously helpful. I appreciate what you do for the community.
