#1 Likely Jasper
#2 Chalcedony? Uncertain.
#3 Chalcedony/Opalite
#4 Again chalcedony, I'd think.

About worth: Not much, I'd say.

Actually, they are probably priceless.

Not the rocks... they are common rocks, but the story that probably went with each and every rock she kept.

I hope you know the history of her treasures.

Gotta wonder about the blue one. Could be a chalcedony as EU thinks but its a bit more like chrysoprase *cant spell it need more coffee*. Other wise I think Eu has it. As to worth well a cutter might appreciate the pieces and you could show them to a rock club but the real worth for me would be in who they came from and the emotions attached.

Chrysoprase is a variety of chalcedony... So...
But it tends not to be such a strong blueish-tint. Rather it's dominant colour is green.
It does remind me of some rough I saw from either Arizona or texas, same colour & also chalcedony. Don't recall the trade name.
So I'd rather just stick with chalcedony & be on the safe side.

Worthy of any personal rock collection imo. I have many rocks I've picked up across the western US. Not many have any monetary value, but the memory of where I was the time I found it is something I value. Those are nice specimens.

The blue is slag glass, goes for about $3 a pound. The others are agate or jasper, and maybe petrified wood, can't really identify them from poor pics.

Value, maybe $1-$5 a pound or so. The fewer cracks and voids, the better the pattern and color, the more use they are for lapidary work.
