Pretty little things. Some unknown

[Seven9]

I know one is Amethyst. I believe the clear translucent one to be Clear Quartz. 

Im very curious about the tiny black one it's almost like it'd be translucent, but it is not just very glassy. 

The green one and orange (pumpkin pie) one as I call it will more than likely be tossed into my tumbler for curiosity. As for the first "stone" it resembles a petrified wood almost.

Anyway, If anyone has any general idea throw them at me please 😊

The one looks a lot like flint to me, and the black one could just be coal.  I would have suggested obsidian, but not being glassy makes me think otherwise. The green one could possibly be fluorite, if you have a uv light try it to see if it reacts.
