Hello! I was hoping I could get some help identifying some items rocks/cabs I have. Any assistance would be greatly appreciated! Thanks! Rock Slab #1: Rock Slabs #2: Cabs:

Those are some nice looking rocks! I am an idiot geologist so take my guesses lightly. But I'd like to see if I am right.
#1 looks like a fossil. It appears to me to be some plant life. Almost like fossilized aquatic plant, in a host rock which appears to be Chert. #2 looks like a Jasper. And it is fantastic material too! I bet it polishes real well. Quick, cab some! #3 looks like classic Agate. But I am too big of a dummy to tell you what kind.

I honestly have no idea what any of them are so any help is appreciated as I try to organize all my stuff! #1 I got this one at Quartzsite this year and the seller didn’t even know what it was. I don’t know if it’s a fossil, but it very well could be. I’ll have to take a closer look at it when I get home and see if I can’t get better pictures. #2 Yeah, I really love this material. I think I cabbed some on the final days of my lapidary class, so I’ll try to see if I can upload some pics later tonight. I’m still quite a newbie at cabbing though, so I doubt I got the shine that it could have gotten with a more experienced hand. #3 Haha, at least you had a guess! All I know is that it resembles a lace agate of some sort, but I can’t find anything that matches and it’s diving me nuts! Thanks again for your guesses! Any little bit helps!

Sorry - no help, but the second one looks like it will cut some nice cabs. It looks in the picture like it might be hard to polish. I would say it looks like Cherry Creek except that it seems to have chrysocolla in it. Definitely a nice slab.

I does look like the second one has some chrysocolla in it, doesn't it? I remember it being a pretty hard material to work with too. I managed to make 3 cabs and almost complete 1 more before my lapidary class came to an end. They aren't the best and I seemed to have gone thru a triangle shape phase with them, but here they are!
I took a few more pictures of the slabs with some better light; as well as the rough for the material to see if that helped with any IDs. I have about 7 slabs and a small-ish junk left of this material, so I'm hoping I'll be able to figure out what it is:
And just to make this post super long, I took a better picture of the 1st slab. I don't think it's a fossil like NevadaBill thought it might be, but I could totally be wrong!

BEAUTIFUL CABS! That material cabs up very nicely. I definitely think it is chrysocolla. Maybe vegasjames has some input on it?

You're probably right on that! I've just never seen chrysocolla look like this.

Reminded me most of Butterfly Wing rhyolite/jasper, though yours has more prominent chrysocolla-filled shrinkage/brecciation streamers than any I can recall. Very attractive! Looks like a stained glass window.

I see some malachite in the stone and the blue is pretty glassy. Looks to me like the blue is silicated chrysocolla, also known as gem silica, which is actually a chalcedony that can be stained with different copper containing minerals including malachite, chrysocolla, rosasite and even turquoise.

Wow, those are some of the most interesting slabs I've seen here yet! I don't expect to ever find anything as nice as that, but if I do, then I would need to come up with some real creative ways of making something out of them. I am not sure cabs would do. Good luck, and thanks again for sharing those!

Interesting. Thank you for the info! Maybe I’ll just note it down as some sort of silicated chrysocolla in miscellaneous rock! It’s better than anything else I can figure.

Looks like a stained glass window. Oooh. That might be a possibility as well! Thank you for the suggestion. I’ll have to look into it!

Good luck, and thanks again for sharing those! It is quite different, isn’t it? I found the one chunk in the back corner of my local rock shop. I honestly stopped slabbing it cause I didn’t want to use up the material. Out of curiosity, what would you end up doing with it if not make cabs?

It is unlimited really. Only the imagination can limit the number of possible creative artistic applications for polished slabs. Only last week vegasjames shared a project that he finished. Scales for a custom knife: forum.rocktumblinghobby.com/thread/86973/ivanpah-valley-goodsprings-trip-linco1nYou know, off the top of my head, I would consider using the material as inlays for a wooden box or small chest. Like a pen box (I have a couple really nice pens), or small jewelry holder at home. How about using them as sides or inlays for a custom desk pencil holder? Or even better, a nice small desk organizer (something that could hold a cell phone up at an angle, and also have side containers for pens or misc small supplies? either as inlays or sides. If I had a lathe, then I would spin up some custom spindles for small appliations, and glue in some metal insets, so I could thread them on to just about anything (a hand cane, a envelope opener, an eyeglass, etc). The possibilities are endless really. I guess it just depends on how much material you still had left.
