Fluorite for the pink-purple. Could be "Tiffany" but I've seen massive fluorite that looks like that and scratches easier.

I finally found a picture online that has that same white spot with the reddish dot and it's a "tiffany" slab
Which from what I can tell is a mix of stuff anyways right?

Yeah, it can look different according to the ratios. I think the purple is beryllium. eta- There is even a red tiffany and yellow. Don't know the make up, though.

First one could be Horse Canyon but I've also see Ochoco moss and even some Hart Mountain green moss that looks similar.
Second - lower grade opalized fluorite (tiffany) has my vote.
Third one - can you knock off a new window? It almost looks like it could be english barite with surface dendrites. You said it was soft but heavy for it's size?

When I get home I'll take some more pictures of the 3rd one It is surprisingly heavy but is really soft. Cut like butter and very messy

Your third rock in the above post looks like chapenite, not Carey Plume.

Thank you Julie I'm more positive now that it's not Barite And now am not sure on the Horse Canyon. I think Tommy is right on his ID And I'm pretty sure my purple one is "Tiffany" I also think Jean is right on yours being chapenite. That's more like what I'm use to seeing with that material

Yeah, it can look different according to the ratios. I think the purple is beryllium. eta- There is even a red tiffany and yellow. Don't know the make up, though. The purple in Tiffany stone is fluorospar (fluorite).
The beryllium found in Tiffany stone is betrandite, but the amount found in the ore is very trace and often not even found in piece of ore. If I recall tight its presence is only something like .04 of the ore, which is one of the reasons beryllium oxide runs around $600 a pound. And bertrandite, which is found in locations around the world is clear to pale yellow.

It easily scratches with a steel knife across the grayish stuff. The purple part is a little harder. It's so confusing

Sounds more like Tiffany stone and the purple fluorospar is silicated.

Sounds more like Tiffany stone and the purple fluorospar is silicated. I know it's way too soft to be a jasper So back to it being Tiffany
