I found this gem here in Montana. What is it? I'm thinking a sapphire? It's about 5 carats maybe.

Hi travisduggins and Welcome.
It would be irresponsible for any of us to try to identify your specimen without more information.

I think your next course of action should be to find someone with some standard gemological instrumentation.
A spin on the polariscope. A specific gravity calculation. Perhaps a spot refractive index reading.
