Looks like you got some interesting color combos in there. But I'm afraid, I'm one of those guys who has no imagination when looking at rough. Need to see slabs.

yes, colors of some imperial jasper. the question will be how fractured the material is. any chance of some slabs to see soon?

Beautiful colors, but I'm afraid I'm with Daniel. The material looks pretty fractured. Be careful when cutting it. You don't want to ruin a blade.

I,m not too sure if some of these will fit on the slab saw. I managed to break the main stone in half and the smaller of the halves is still 16.5x10.5x10.5 inches. If I get a chance today I will run by the club shop and see if I can cut a chunk.

I/m sure that you can examine carefully and find some solid slabs (small or large makes little diff), but count on lots of frustrating passes with the saw and some very irregular pieces coming off when working it. None of this discounts that there is some beautiful color and form there, its just that it must be dug out diligently. I keep collecting small jasper nuggets with the goal of a few giant jasper tumbles someday, and a hope that a few pieces will result that my wife will never want to part with once presented. Am I a dreamer? Tom

Holy crap... looking at the black lines, I think you just trashed a tiffany stone... GAAAH.

You've ound some beautiul specimens! Even though many are ractured, they are still beautiul! Those are some gorgeous color combinations. Thanks or showing.

Am I a dreamer? Tom I know right where there is a large solid looking boulder of jasper (red and white). I found it on my last trip, but I had already been collecting for a while and had to get going to my second destination. When it cools down though I will make another trip up there. Or a few friends are talking about making a very early morning run to beat the heat, collect a few hours then drive back.

Holy crap... looking at the black lines, I think you just trashed a tiffany stone... GAAAH. No, none of that is Tiffany. Its all Jasper. I have collected quite a bit of what I have been told by a number of people knowledgeable about Tiffany that what I have is Tiffany stone. I have only come across one piece though with the black manganese lines. Otherwise the rest is the fluorite, calcite, opal, quartz, etc. associated with Tiffany stone. I know there is some controversy of what actually determines Tiffany stone, but people need to keep in mind that Tiffany is not a singular mineral, it is combination of minerals that can have slightly different compositions just like all the different compositions of jasper does not mean certain ones are not jasper. Here is a large chunk of what I was told was "old stock" Tiffany:

I found some smaller pieces that are actually solid so I am hoping that there is some solidity in the centers of the larger chunks and that much of the fracturing came from people simply smacking the rocks with sledge hammers and picks. I did find some larger boulders that look really solid that other people have not hit with anything so I suspect that at least some of the fracturing is from that. I would lover to take a big gas powered concrete saw up there to remove some large chunks without smacking the rock with a sledge hammer.

I dunno... that 'old stock tiffany stone' looks less like tiffany stone than the one above. I saw a pix some time ago of these insane multicolored tiffany stones that looked a bit like your big one. Found it... this was from a blog I found on the net of this guy at Quartzite's Tiffany Stone. Grant you, it's not just like yours, but it does look a bit like it with the colors. Of course, you'd know how hard it was, so if you think it's jasper that's probably it, but this piece was reputedly pretty hard too, based on a thread about it on the lapidary gemstone forum: In either case, you found some beautiful rocks:)!

The Tiffany is a funny one... but from what I can tell, the one shared trait is those black lines. I have several of the purple, because that's the most common color, and possibly different ones. Here are a few of mine that I think (but are not 100% sure) are Tiffany stone: Pretty sure: Pretty sure: Pretty sure: Not sure, but looks like it: Not sure, but some people think it is: Do you have a slab saw? If you can cut a slab or even cut it in 1/2, it'd be easier to figure out:).

They sure look like Tiffany stone. Again the composition can vary quite a bit. For example, the last specimen you have looks like it has limonite (iron hydroxide) around it, which I see a lot of where I collect.
Your third specimen is mostly white, which is not uncommon and has a more superficial layer of fluorite. The white could be opal, but is much more likely calcite. You can put a drop of acid on a chip of it or pretty much anywhere where it is white to find out. If it fizzes it is calcite. Just rinse the acid off right away. I generally use HCl, but vinegar should work as well.
The fourth specimen does look like the pink Tiffany I have seen in jewelry. Rarely see it, and if I recall right it was considerably more expensive than the purple Tiffany.

Forgot to add that I don't have a slab saw, but have access to slab saws at the gem club.

Well... it's a pretty color!!! That last would be really neat if not for all the cracks:(.
But... you could stabilize those fractures with epoxy before you cab if you want to go through the trouble. I'm sure there are some really pretty cab spots in each one:).
