OK, I'm new to this and my wife got a rock saw and tumbler so I am trying to look for rocks for her also. See if my guess are even close.
1st pic, my guess is limestone, but has a crystalline structure so might be a kind of quartz. Dont think this will polish.

2nd pic my guess is quartz from a vien, is this what I look for to find gold? Should polish nicely

3rd pic Not sure if it is quartz or limestone, but has iron pyrite, and could it be a little gold?

4th pic I think this is classic hematite, should polish up nicely.

5th pic I think this may be a kind of hematite, but it has a definite grain structure (see the top). Also looks like some pyrite.

6th pic Definitely shiny and crumbly in layers.. I think this is all iron pyrite, but has no gold coloring.
