I found these two rocks this morning when i was walking my dogs. The first one i thought that i had at last found my first Agate. After i cut them i do not think i have, looks like i will have to wait a bit longer to get my first Agate!!!! Can you tell me what they are. Is the first one a Chert or quartz. And is the second one a kind og Granite. Also can i tumble them as they are? I can only get 1 picture to attach?  This is picture 3 of 3 I cut this rock into slices, to see what the inside was like. Some nice looking markings. But whay is it |

Hard to tell by the pictures. The first picture you posted looks like a breciated jasper, the brown could be a jasper also. Grey one could be an agate. I'd go ahead and tumble them. If anything tumbles away too fast remove from mix. Out here "chert" is often used to describe a solid colored chalcedony. Don't feel bad about your pictures, I'm still trying to figure out how to put the film in my digital.

How hard are they? They both look fairly jasperish to me.

I can't help with an ID but a simple scratch test with a piece of file or GOOD quality knife blade will tell you if they are good for tumbling.
