What ever it is, it sure looks interesting.

Green crystals could be Pyromorphite. But that's just a guess.

I'm pretty sure I've got it now after looking at the specimens you left for me to look at. Your host rock is composed of primarily of Gneiss. The green color in your specimens is likely coming from Chlorite, Actinolite or other green amphiboles that are part of both the gneiss and schist formations in your area.

Thanks BB but the hardness doesn't add up as Chlorite should scratch since it is 2 one half to 3 on mohs scale unless its under the hard material and doesn't look like it is through loop. Just a thought. Not talking about this mint green crystal I posted but the Hexagonal crystals I had in another post. This mint green material is more granular stuff so I don't know.

Does that green stuff come off pretty easily? It does on the specimens you left for me to look at. It crumbles right off; very soft.

Thanks a lot BB. The crumble could very well be a softer mineral and I will surely recheck the stones but some are crystal shiny and are in the stone its self and I cant scratch them with a known piece of quartz I have. I guess all of them are not the same mineral. Thanks a lot for your help in trying to figure this out. I need to take the hard ones to a geologist to find out for sure. We will get there.
