Cutting Open More Rocks, Agates, Jasper, Calcite.

Cutting open more rocks I either got from rock sales or garage sale on my 10" Hi-Tech diamond saw. First one is a agate. Note sure what the second one is but I think it is an agate. Third one is a green jasper I got from my uncle's garden. Forth one is a agate. Fifth one is a calcite, I think it is a travertine. And the sixth one I have no clue, very light and grainy.
