Well I am sorting through my recent 27 pound slab purchase and these are a few that I am unsure of. Any help would be appreciated. I hate selling cabs/jewelry without knowing what a stone is. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. Thanks Chuck

#8 and #9 were identified as prudent man by Tommy but I added better pictures here to be sure. Chuck

Is 12 a fancy serpentine? They are all winners.

Yes. Isn’t ricolite a variety of serpentine?

1. Aztec Lace?
2. not much green, but I can't help thinking Plasma
3. fossil shell in marble?
4. could be Myrickite
5. lepidolite
6. dendritic opal?
7. Imperial
8, 9. agree Prudent Man
10. Biggs
11. Blue Biggs
12. agree with riccolite (gets spelled with both 1 and 2 c's; yes layered serpentine from NM and AZ)
13. Spiderman
14. marcasite plume
15. charoite?
I intend to come back, if I survive dinner, and look more closely at others if any are left to ID. Came back with a few more. Now for some ice cream!

1. Amethyst Lace (?) 2. Old crazylace agate 3. devils toenails (?) 4. Plasma agate with an abundance of cinnabar 5. (?) 6. (?) my first thought was Paiute Indian dendritic agate but missing some colors 7. ( agree ) Imperial Jasper 8. Prudent Man vein #2 (green) 9. Prudent Man vein #1 (original red) 10. ( agree ) Biggs 11. ( agree ) Blue Biggs 12. probably what the others said - layered serp. *but* is it translucent? If opaque could be Lizard Stone from near Burro Creek. 13. ( agree ) Spiderman jasper 14. ( agree ) Nipomo plume marcasite 15. Could be Mexican Purple opal - the matrix is throwing me off 16. Laguna Lace agate?

Thanks for all the help everyone. I am happy to hear that is Biggs Jasper. Got 4 or 5 nice slabs of that in the mix. Cinnabar is really toxic right? worse then bumblebee jasper?

1 seems to be Mexican crazy lace cut across wise. But I cannot be sure. Can't zoom on my phone.
Edit: opened image in another tan to escape JavaScript of proboards prohibiting zoom on mobile. Looks very much like crazy lace cut across the grain.
4 is plasma with lots if cinnabar, I agree
6 is Amethyst sage
15 is Tiffany

I am happy to hear that is Biggs Jasper. Got 4 or 5 nice slabs of that in the mix. Cinnabar is really toxic right? worse then bumblebee jasper? The #11 Blue Biggs looks to be a primo slab - will sell for $$$ if face polished on a flat lap. You got some great pieces there. As for cinnabar, if it is bound in agate and/or opal (as in Myrickite), it is quite difficult to separate the mercury from the agate/opal that encapsulates it. If it is cinnabar in serpentine (aka, "Chicken Bloodstone"), you need to exercise more caution (see this link). Myrickite and Chicken Bloodstone are different than cinnabar ores, in which native mercury can actually bleed out and is/was mined because it was so easy to extract mercury. They are safe to wear (just like cinnabar and mercury containing lacquer, paints, ceramic glazes, mirrored glass, fire gilding, etc. that we encounter where the mercury is bound-up and fixed within other materials). I'd still avoid excessive heat when working either (heating is how mercury is extracted from pure cinnabar ores) - use lots of water and avoid breathing in the dust.

Wow, you scored some beautiful slabs Chuck! First slab is Luna Agate from Mexico. I think most of the rest have been identified. Very nice!

1. I'd go with Crazy lace. Aztec is more purple and/or yellow. I've never seen white.
15. doesn't look like charoite to me. Charoite looks like purple seraphinite. I agree that it's probably Tiffany, although it looks different than any I've ever seen. Banded like that is new to me. If it wasn't for the matrix, I wouldn't recognize it.
@ rocks2dust, what makes you say Imperial for #7? I can see where it could be, but with the Biggs in the collection, I would have guessed Morrisonite or Willow Creek, which could conceivably look like that. Those just put me in an Oregon state of mind, I guess. :-)
In any case, there are some gorgeous slabs there. Enjoy.
As for toxicity. Yes, be careful with mercury stuff, but keeping it wet, you should be OK. As for whether mercury is worse than arsenic, that would be tough to say. Luckily, polishing machines have water jets, so you won't have to lick either one.

I can't help with much, but I can only say #1 looks like a bunch of the Mexican Crazy Lace that I've gone through lately. I'll clearly admit I can be wrong.

Agree with Luna agate for #1. There are some terrific slabs there!

I can see where it could be, but with the Biggs in the collection, I would have guessed Morrisonite or Willow Creek, which could conceivably look like that. Those just put me in an Oregon state of mind, I guess. :-) Not all cuts of charoite look like seraphinite or are even very chatoyant. May turn out not to be charoite, but I've had some that looked like this piece (lots of white in the swirls with that yellow/tan-to-greenish near the rind). If charoite, should make itself known right away during sanding. As for #7, I also considered Willow Creek, but said Imperial based on the color of the red (the reds in WC tend more toward mauve; in Morrisonite and Carrasite, toward brick and less commonly monochromatic) and the greens at the edge. Beautiful pieces, whatever they are.

I completely agree with R2D that #7 is Pink Imperial Jasper from Mexico. I have a lot of it and your slab is nearly identical to my material. I don't have an image of a slab but here's a cab from the material for comparison:

15 reminds me of some purple opal I had out of Mexico, but I can't remember the name of it.
