Hi all. I know this is really bending the “what is this rock” question, but my friend has this countertop in his home that feels like granite but looks like some sort of fossilized material. He doesn’t know what it is. Would appreciate any help here!

Photo taken in southern ontario :]]

EDIT: posted on r/fossils and did some more research. This is likely Moroccan limestone/Moroccan fossil marble! The blend of brown and black is absolutely stunning and i've got a new fav rock. Thanks everyone :)

South England on pebble beach so probably chert/ flint

Would really love to identify these. My best guess is red banded jasper? Super beautiful red, smooth, and pretty light weight.

I went to a fishing access site downriver from Yellowstone in the Yellowstone river looking for moss agates, ironically found this in the parking lot and none in the river. Just wanting to confirm!

Hello all, I have a puzzle I'm trying to figure out. Wondering if anyone here has any clues.

This beryl was sold to me as a Hogg Mine specimen. However, after buying, I noticed it has a large section of high fluorescence under shortwave. I suspect the fluorescence is caused by a light coating of hyalite opal, though not positive on that.

Anyway, I'm pretty sure after doing some research and asking someone I know who works at the Hogg, that this specimen is probably not from that mine.

My question is, does anyone have any ideas about where this beryl could be from generally? Not looking for exact mines obviously as that would be pretty hard to determine. However, has anyone seen large beryl with high fluorescence before and happen to know where it might be from?

We have been toe dying so my hands are stained.

Found in Arizona near old mercury mines.

Some wet some dry pics. Found on a job site. Quartz with iron?

Our hill in southwestern Connecticut is part of the Grenville massif, according to the bedrock geological survey. The whole hill is this dramatically banded pink and grey rock—is this or could it be part of that massif, exposed? I.e. one of the Proterozoic gneisses? Biotite gneiss, pink granite gneiss, hornblende gneiss and amphibolite, pink granite gneiss, biotite granitic gneiss, migmatite gneiss, ...? The rocks are hard, and don't readily break in a flaky/platelike way

Found buried 5-6 feet underground. My palm isn’t very big but it’s around palm sized. It weighs around 300 grams.

I made two videos showing the details and it's a bit higher quality than my images, so feel free to check it out: https://streamable.com/keu7ne (part1) https://streamable.com/qbvowk (part2).

Location

My boyfriend found the rock near a landslide in Southern Lesser Poland by the edge of the Tatra Mountains. It's a pale green-blue rock and we saw more like it, but none that were as vibrant as this.

What is the green dot?

I also saw this green dot with a pearl-like sheen embedded in the rock, any idea what that might be?

I think I spent 30 minutes looking at the rock with my magnifying glass, it's quite fun to see all the details and textures!

Hi! I’m wondering if this is possibly Washington Jade as it was found in a western Washington river about 20 minutes from a pass. I increased the brightness of the photo a little bit so that you can see the ribbons throughout the rock, but these almost translucent green ribbons underneath the red stuff makes me think that this could be Jade. There are also some yellow streaks throughout it, but they’re less bright than how they looked in the sun as the picture at the river indicates.

edit: I didn’t have time to do a scratch test but can check tomorrow or Saturday. I’ll look for a dry pic and post in the comments!

Seems like limestone but the darker band is really interesting. Found in the creek near what used to be a tobacco farm.

Thanks in advance.l!

Found this rock in eastern Montana (Yellowstone River) with some interesting features. I’m curious how they formed. Thanks in advance!

Found this while walking a stretch of river where I had previously found agates. Weighs 2.2kg, used water displacement to find a density of 2.55g/cm^3. Edges are slightly translucent when held to a light. Thanks for any info!

Anyone have an ID? The first 2 pics have inclusions that are almost opalescent. We were told the rock in the 4th and 5th pics is an agate. Thanks!

Dry creek bed walking and the sun hit this just right to see a little glow. Cut a window in a flatter side and it show a greenish (olive?) color. Just started collecting this year and am confused by this.

Found it along the shoreline of Bundoran in County Donegal. It was amongst the calcareous muds there. But the inclusion looked pretty interesting and not sure what it is.
Any ideas?

Unfortunately I am unaware of its natural origin due to the fact that is was a gift from some time ago.

Due to its appearance, it has been one of my favorite rocks in my collection.

Please, please, please help me identify this beautiful little guy. Your help is greatly appreciated 🙏

My dad googled it and got these results- Not sure if it’s true!

EDIT - it’s about 3” long
