Little green streaks in stones
Hiking in Colombia hundreds of km away from the emeralds area with my father in law, we found big stones with little streaks that tend to be of a color similar to turquoise and other little stones with a bit more of green and dark green. We'd like to know what they could be.
Edit: Now I'm curious about the blue greyish streaks in the other stones. I'm adding more pictures.

Grey stone with little green streaks
Big rock that we found next to the trail that got our attention to look for the small
Fibrous malachite perhaps? Just guessing
Is the green hard or crumbly?
Edit: It's not as hard as I tried the first time because I crushed a spike of the little green stone with my fingers.
It's easier to crush the white rock than the little green stone or streaks.
I'm adding more pictures in another reply.
Gonna need more pixels to know for sure.
