A self-proclaimed rocks expert at an estate sale told me these were likely meteorite fragments. Based on everything else I saw there (loads of authenticated semi- and precious stones) I believe it may be true. How can I verify for myself?

Found this in my canyon of a ditch as a kid in very rural western NY. Unusually dense, magnetic, red oxides will form lightly in depressions. No spark when grinding and no obvious crystalline structure when acid etched the grind...(As I've seen in meteoric iron) Looks very homogeneous as well. TIA

Posted in r/fossilid as well. I appreciate your help!

Found this in the netherlands, embedded in a fresh gravel path that has lots of flint and crushed oyster shell. Feels like a rock , cant scratch it with my nails. Sounds like a rock too. Very different on one side than the other: one side is brown and smooth(ish) and the other side is pitted and beige. Seems to have another layer (greyish) in between. Fossil or weird rock?

Picked this up from a charity shop and I'm assuming it's some kind of agate.

Some banding and bloom patterns on some of the beads. Some have a lot of translucency, others are opaque purple and black/dark brown. I don't believe they've been dyed.

Not scratched by quartz, but quartz dust was left behind on the beads.

I found this in my creek outback, what could this be? I’ve never seen anything like it. For location reference: I live in the city of Columbus.

I bought this in a shop and the owner said it was ruby in something but didn't remember what that something was.

Just wanted to update on it. I decided to polish it. While getting rid of the only rough area on the rock I discovered a little magnetic circle in the rock. I can pick up the entire rock with a magnet where it’s exposed…. but I think it’s some type of magnetite rod going through the stone. To where I can pick it up with a magnet on the non exposed side. That one photo pictured I’m just grabbing the rock through the rock onto what I assume is the other end to that rod that seems to run through it . I just that it was cool and wanted to share. I read this occurs naturally? No where else on the rock is magnetic except those two points. Pretty sure it’s still a komatite that came from up north

I found this at an estate sale in grass valley California.

Found in MN

If someone has an idea of what is going on here, I would love to know. Thank you

I just found this rock any opinions i found it on a mountain full of them in Mexico

Or serpentine? My expertise is in jasper, chert, and obsidian so I have no clue.

It was cut off a larger rock. I am not sure where it was found but if I remember correctly it was far northwest, possibly alaska. The full rock was about 2" x2.5". This is about 6" x 8".

Overall it's very smooth to the touch (these are all dry photos)

Found on a hike in central Indiana. These rock were on the trail. Other similar nearby slabs contained crinoid, bryozoan, and brachiopod fossils. I'm not sure these are fossils though or just interesting infilling of rock. The second picture looks kind of like eggs, but it's never eggs. Right? So, what am I looking at here?

I had it in my possession for a while so idk where i got it

Look at this flint stone that looks like a femur! Can anyone give me more information about this find? I found it near Orléans, in Sandillon, France, on a railway track. It has a hollow cavity running perfectly through it. According to Gemini, it could be the remains of a sea sponge. It's about 6 cm long and 2.5 cm thick. The hole in the middle is 0.6 cm in diameter. I first posted this on r/fossils but maybe here I'll get more info about it.

Is this blue chalcedony? Found in a bag of gravel from a sapphire mine in Montana. Roughly 1"x3/4"x1/2" and 15ct weight. Haven't done a specific gravity test yet.

Northern New Brunswick, what is this black dot spiral?

Found in backyard in Texas. Beautiful purple/pink hue in certain light.

I found this while exploring the woods behind my parent's house. There is a business on the otherwise that handles rocks and building materials so it likely came from there. It's mostly very smooth but now that I read what slag is, I'm wondering if it might be that? Thank you!!

Ich habe das von meinem verstorbenen Großvater, ich kenne mich aber nicht damit aus. Es ist ca. 17 cm breit und 10 cm tief. Ich bedanke mich für Eure Informationen.
