Are all of these jasper?

I recently bought red jasper from two different sellers on ebay. The first two pieces in the pics look like what I would expect with smooth waxy? surfaces where they were broke. The second has rougher surfaces. The piece farthest to the right is the one with the rougher surface. Not sure if the pics will show enough detail. The rougher jasper is supposed to have originated from India. The seller has a lot of good feedback.

I did add a fresh break to a piece of the rougher jasper but I misplaced the piece. It looked rough like the one pictured anyway. I did notice it was harder than steel because it left some steel residue on it when I first unsuccessfully tried to fracture it.

Yes, that's Jasper. Jasper is an opaque, impure form of silica. The deep saturation of red is from iron oxides.

Ok thanks, thought jasper always had smooth surfaces like the first two pieces where it fractured. The last piece has a rough feel. Thought it must be jasper though because the seller deals regularly in stones and has good feedback

Some have a rougher texture; simply put. I find many various forms of Chalcedony and Jasper here in Tennessee. I prefer mining stream placer and bench deposits and because of that, many of my specimens are naturally tumbled and polished by the flow of water. If I go collecting Chalcedony at the top of the mountain, out of the flow of water: I find large, rough-textured specimens that have not been exposed to degradation yet.

Ok, appreciate your replies. Makes me feel better about using them. I'll give carving them a try once things settle down for me.

Sounds like fun. I would like to find some jasper where I live. Supposedly you can find it on some beaches and probably in rivers. Aside from maybe some of the stuff in the Upper Peninsula I'm guessing it is all glacially deposited here. Have a few possible pieces I'm unsure of. Maybe I'll post them on here someday.

There are a lot of very fine agate varieties in Michigan!
