Hi everyone! I'm new here. Need help identifying thunderbird pin and hallmark

I’ve searched quite a bit but haven’t found any pin/pendant quite like this one. I inherited it, and believe that it was purchased sometime in the '80s or '90s. The hallmark looks like the letters VA with what looks to be a pipe underneath. I would appreciate any insights on the origin of this piece as well as the type of turquoise and whether I am correct in assuming that the cabochon stone is coral (It looks a bit more translucent than most coral, though.) Thanks!

This pin is a Peyote Bird which is a symbol of the Native American Church. The stones appear to be not real, most likely a plastic. The item has been cast and I am not familiar with the artist’s hallmark. Thank you for sharing.

Hi, not NA made. Southwestern company Carolyn Pollack [thus the copyright symbol and 925]. The top initials would be that of the artisan she contracted to make the piece - usually a NA. The hallmark is for Carolyn Pollack Relios - company name.
