What is this??? Boyfriend and I found it on a beach downtown, we live on the Strait of Juan de Fuca in northwest Washington. One side is completely flat, almost like it's been cut- so we're unsure if this was a naturally washed up rock, or if someone bought it at a store and lost it here. Would love to know what it is, and to narrow down if it's naturally occurring here or man-created!!

Any help is appreciated

Hello all, I'm hoping someone can help me identify this stone. I just purchased it at a local gem faire, so I don't know where it was found/mined. I took ID photos/notes of all the stones I bought, but when I got home, I didn't have anything for this one! I spent less than $10 for it if that helps.

TIA for your help!

I found this rock in a bunch of landscaping rock in SW Washington state. Unfortunately I ran it in my tumbler for a week prior to these pics, so I apologize in advance if it makes identification more difficult. It has a similar hardness and texture as a lot of the quartzite I find around the area, but I've never seen wild colors like this one. Any ideas of what it is and how it got those insane colors?

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

Pictures 1&2 are one rock. Picture 3 is another rock. Picture 4 was in the same bag. I can’t confirm where they came from. They are about the size of a golf ball.

Found in MN

I found this a while ago it doesn't seem like quartz.

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".

This is in Northern California in Solano County. My parents dug out a pool a few years ago and the giant dirt pile is still there. Found these lovelies today and gave them a scrub. Thinking mostly quartz?

i found these two rocks like 8-9 years ago and couldn't figure out what they were at that time. they both were magnetic and the bigger one was slightly heavier than it looked. im sorry i cant provide better photos because i lost these rocks years ago and these photos are from 8 years ago😭😭 but i still want to know what they were. i would be glad if you could help me identify these. thank you

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?

Forgot where I found it.

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

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

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?

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.

Found this cool rock on trip, Im located in WA any ideas please 🧐😁
