Magnetic? Hardness?

Grey streak can be indicative of galena, it can look a bit like native metal sometimes too.

EU Citizen's tests should confirm it. Also, smell it for sulphur, might need to scratch it a bit.

I was thinking pyrite/Marcasite at first. Will a knife scratch it? If not, I'd stay with pyrite/Marcasite.
