American turquoise? International turquoise? Chrysocolla?

Howdy guys, this piece has very vibrant, multi-color stones. The ones on top near the terminals look like American turquoise to me (I know very little about turquoise), but the ones on the bottom almost have a chrysocolla look… I’ve seen some beautify chrysocollas in Peru. Any ideas? Again, I understand these are only educated guesses. Thank you all in advance.
PS: it’s marked 925 instead of sterling, and it’s not hallmarked.

Some of it has a Sonoran Gold look to me.

Do you think an artist would mix turquoise and chrysocolla? I can see the Sonoran Gold look as well. Thank you!!!

I wouldn’t think so. I have never seen it done.
