specimen

I'm wondering if this is calaverite , pyrite, or galena. It is very soft - but not as heavy as gold. It shines like silver and gold. Any ideas? Thanks for any feedback.

Not exactly sure if this is even what i think it is but if i believe to have found a specimen how do i go about getting it analyzed? Any info would be greatly appreciated and thankyou in advance for your time!

In this case, amphibole. After some etching off the calcite, I'll grab a nicer picture of the specimen.
