Is this Navajo?

Beautiful piece, unsigned, and unmarked.
I think it is a brooch? I mean, I’m sure its a brooch, but not really sure what the extra pin things are for.
It tested as silver.
Please help!

I’m pretty sure it is not native as they aren’t big into faceted stones but the gold and amber go nicely together. The pin on the back is self explanatory but the two pins look like they are meant to be slipped into a pocket or over a collar. It also looks like it could be hung on a chain. No hallmarks that I can see, would be interesting to know what it’s gold and silver content is.
Interesting piece.

Thank you for your quick response, and I apologize for my delayed response. I was able to find that this brooch is sterling silver. The gold is just an overlay atop the silver.
