What do you call this style of collar?

I found this picture in the Finds & Deals section. Wondering about the collar. Thoughts? I’ve never owned this style.

Thanks, T4

Vanson calls it Beaded leather collar.

I don't know for sure if that's the official name for it. I've heard others refer to it as a band collar.
