Chrysoprase? and quartz piece ?

The first 2 images show a rounded pastal coloured brown and green rounded stone it looks very like chryoprase examples ive viewed? i think the next piece is quartze ?

And the last image.

First one you're calling chrysoprase looks like a flint or jasper to me. Second might look like a chalcedony - a variety of cryptocrystalline quartz. But to be sure you might need checking the hardness - such a peeble might be some other waterworn mineral like calcite, barite etc...

They both look like some kind of chalcedony, but the first one looks more like flint or chert to me.

I aint calling it nothing yet Sergey theres a question mark and an it looks like bit in the post you must of overlooked mate

Sorry something whent wrong there, the hardness well ive tried scratching the green- brown pebble with a knife it leaves a mark that looks like the metal of the knife? as for streak again it seems the stone is just scratching the back of a tile, ive been rubbing it up with wet and dry for a few hours now, the green and brown is coming up better but other wise its hardly touching it!
These pics are after about 4 hours rubbing with wet and dry.
