Found in central Mississippi in my yard(for reference on the appearance before cleaning up it’s on the top of the bag of dirty ones in the 3rd image )

She didn't pay much, I'm almost certain it's stone/gem (doesn't get warm easily, unless it's glass??).

It doesn't get damaged by metal, and it's slightly translucent under a light (but barely, it's very opaque).

Usually bracelets like this are made by dyed agate, but I'm not sure it is.

Any thoughts?

The second picture us from a microscope, it has some tiny crystals scattered here and there

Can you tell me, what this is? My brother found it in his garden in Hildesheim, Germany.

These were all found by my grandpa on various local beaches in Humboldt County, Ca. He's also the one who tumbled them. I'm getting either green garnierite or moonstone as answers to the 1st. 2nd I'm assuming is some type of brecciated jasper. 4th one has a million different answers when I image search it. 5th one looks like polychrome jasper, or bloodstone, but obviously that's not geographically possible, so 🤷‍♀️ i have a ton of different jaspers, but I have like maybe 3 or 4 that look exactly like this one. 6th one (more purple than appears) gives me moonstone with an imagine search, until I turn it over and it's like a whole different stone apparently. I genuinely thought 7 was an agate, since it looks like a ton of other agates I have, but light doesn't pass through it at all. Image search answers for 8, 9, 10, 11, 12, and 13 were all "moonstone". Unsure of the others, but 12 and 13 (last 4 pics) look like jasp-agates to me. Oh yeah, these are all smooth btw (since they've been polished), so they all feel the same. Pls help a girl out lol

Found in Everett, WA: the distinct black striping reminds me of a shell. Is this a clam fossil or something?

For context, these were all found by my grandpa at various local beaches in Humboldt County Ca. He tumbled and polished them. To me, they all appear pretty similar (especially the last 2), but only the 3rd one passes light through. Not sure if the first is just aventurine or what, but image search is extremely unhelpful, so any ideas?

Couple more from Grandpa's pile I think this one's obvious enough though I'll be donating the big one

I recently inherited my grandmother’s rock collection and I’m hoping to learn a little bit about a couple of pieces. Thank thank you in advance!

I find these in a nearby river all the time. They're blue in the water and grey when dry. Smokey quartz maybe?? Thank you!!

(My camera is broken, apologies)

It’s from Brazil!

Smokey quartz garnet and peridot?

I recently inherited my grandmother’s rock and crystal collection and I’m really curious about what this one is. Thank you in advance!

They were found on walnut beach in ct

My camera and the light does the yellow no justice.

Found in Garfield county Colorado near East Rifle Creek area where two old uranium mines are. It was in a pull-out a couple miles south of the mines.

I've explored a 15 mile radius around the mines (never been able to explore the mines themselves because the owners do not allow it at all and there are cameras), and have never seen rocks like this in that area.

The yellow is powdery, but not easy to scratch off. From what I understand, carnotite can get in between the smallest spaces of sandstone and over take it so that it looks like sandstone? A couple areas of the yellow it appears like a crust, the rest is like it's sandstone. I believe the black bits are carboniferous trash.

I know a Geiger would tell me immediately, but until I get one, I was just seeing if anyone who has explored Colorado/Colorado Plateau uranium mines has seen anything like this before, or knows exactly what it is.

I bought this from a rock cutter in New Mexico. He said it was Bisbee, but it doesn’t look like the Bisbee I’m used to seeing. Additionally I’m now wondering if this is some kind of dyed howlite or something due to the lack of spider webbing.

Did I get ripped off?

My uncle found this rock near to a river in the mountains.
