Some of your answers are correct. I found a printable rock guide on the internet that has helped me tremendously. I will give you the website address in a future post.

The second one is Mookaite (A form of radiolarian chert found on Mooka station in Western Australia) a large focal bead with Mookaite chips, In the USA some folk call the material Mook Jasper.

From Left to Right: Carnelian, amethyst, green adventurine, sunstone, mook jasper, chrysocolla, snowflake obsidian, mahogany obsidian, and picture jasper. There is a brown stone pictured individually that does not appear on the group pic of stones. I do not know what this one is! Help anybody?

i do not think that is carnelian . it looks like pink feldspar - can't be sure, but not carnelian. I also have not seen mookite like that red rock. I have cut lots of mookite. I am fairly sure about the lepodilite. I have pounds of the stuff.
... and the picture jasper is African Queen picture jasper.
search up pics of the names and get some more opinions

Thanks Dan. I don't know what mookite is - I was basing it on what someone else said. I thought the red stone was a red jasper. What does lepodilite look like? And the carnelian? I have about 3 stones that look just like the pics in the rock ID guide I printed from the internet. It's more peachy then pink. I continue to learn....

The dark red one looks like bloodstone to me. I've seen some that's mostly red like that, with that kind of dark green (rather than green with red like most bloodstone). It's the right color red. But it could just be some random jasper. Looking at it again, hard to tell from the photo, but it looks mossy . . . so some kind of red/green moss agate maybe.
So going in the order of the the big pics, looks like we have:
-African Queen -Bloodstone maybe (or jasper or moss agate) -snowflake obsidian -Gem silica maybe, or chrysocolla. The criss cross lines look like gem silica (quantum quattro sometimes used as an identifier too but I don't know much about that). -? -Mahogany obsidian -Definitely lepidolite (nice piece) - the sparklies are the giveaway -Aventurine probably - Maybe orange calcite, orange feldspar as noted above, or orange aventurine.

yes, the other oranges Susan mentions make sense. What rules out carnelian for me is that it is almost always darker reddish brown, and when lighter gets a yellow/amber tone. You never see the kind of whitish peach swirl in carnelian. I might go with orange adventurine if it is hard and orange calcite if it is softer. On reflection, orange/pink feldspar often has the appearance of lines/threads in it or even the witish edges of a cleavage plane. (But sometimes ther are larger clear orange pieces.) Here is one feldspar pendent I made as part of a batch of 400 for a kids event several years back: I thought about bloodstone for the red one, but there seemed to be a very tight mossy texture, where bloodstone is more uniform. but bloodstone would be a better ID than mookite. It is likely just an unnamed red moss agate. FOr the standard lapidary materials Ron Gibbs book (and website) on Agates and Jaspers is very useful. I find also google images is a great way to get lots of pics of a large range of stone appearances. Lepidolite can be tricky because it is not all purple, and the purple can be more flaky/sparkly or more dark and gemmy. ut the lighter lavender rough is the most common. For example: www.greatrough.com/rough_lepidolite.shtmlI'll try to post a pic of my lepolidilite chunk tonight, and if I can find it, a small pendant that has been through rough grind.

I am surprised Lepidolite has a mohs of 2-4 I tumbled it with rock that is much harder. I'm surprised it turned out so good!

With some of the softer lepidolite I have cabbed I found I got my best shine by hand work. I used a rubber backed polishing disc from my cab machine. After doming cabs with 220 belt on expanding drum I used a 1000 grit disc of s/c paper then on to 2000 grit and ended with 3000. I did 4 cabs while watching TV in less than 1 hour with a little spit for sanding it in a circular motion. They were not on dop sticks but have done some with sticks attached. I did some baby lagunas that way also. Attachments:
