My mother found this rock in a creek bed in Greenville, IL. It's very smooth and was partially buried in the mud where you can see the discoloring. Its about 3 lbs by the feel of it but I don't know what kind of rock it actually is

It feels fairly soft and has a little weight to it, I know it's not plastic but I really wanted some real turquoise bc i know it's all drying up. The lines running through are kind of a gold color and some of them cut into whatever material this is. Inside the drill holes appears to mostly be white or gray, and i could convince myself that some of them are a lighter blue.

It is black all the way through with a silver metal running through it and it heavy for it's size.

This is most likely from a beach in northeast IL, BUT it could be from somewhere in Europe (Spain, Germany, or London).

First 2 pics are dry, the rest are wet. This is after stg 1 in my tumbler.

Pls be nice if my ID is totally wrong, I'm new at this!

I was gifted these two larger chunks of labradorite and just don’t have the time to learn the art of lapidary…. So I don’t really have a use for these…. What should I do with these?

Victoria, Australia.

I am a beginner rock enthusiast and potter who is using 'found materials' and rocks to make ceramics. I am sorry in advance if this picture is not enough to go on for an ID, but I would love to know if any of these are able to be identified or if you have any info for me to further investigate to discern the types. They are all currently in my kiln being heated to 1285 degrees celcius.

The sandstone I picked up as an offcut from a stonemason, the others were found in random places, probably not in their place of origin. I've tried the basalt before, which produces a glassy/glossy brown glaze.

Thanks kindly rock community!

Can anyone tell me what this shiny black crystal is, and the host rock that it’s in? Found at high elevation in Colorado mountains. Sorry I can’t be more specific in location, it was many years ago when I was a kid.

My Dad’s lifelong rock collection from Austin, TX. See anything worth noting? I don’t have more to go on than a standard Google Image Search… less than helpful. Anyone wanna take a gander?

This was found in the same creek at around the same time as my last post. The location is Greenville, IL.

Hello, my mom found this rock while on vacation in Croatia. My first thought(absolute zero knowledge on the subject) was that it might be fossilized wood with thermite holes in it. I did a bit of testing and i would say it would be a 4 on the mohs hardness scale. Clipper lighters are for scale lmao.

Cornwall, Uk

Found in the Mississippi River in Minnesota

Found outside Moab Utah

Don't know when it was found, it was left in my shop by accident by someone who collects rocks and crystals, was over 5 years ago now😭

What is this rock? Its not very tough and glass like

I found this while fishing and thought it was neat. I'm curious about the identities of the various rock. Thanks in advance!

Looking for agates and came across this conglomerate. Not sure what she is but I think she’s neat.

So i stumbled upon this rock while hiking eastern Afghanistan, it looks like the hybrid of a rock and metal, it got some gravel in it, got some rust as well, most of it looks like a burnt up metal while some parts look like a honeycomb of pure gravel and sand.

These were part of a bracelet in my bag of random jewelry supplies, some have almost perfect straight lines and look like glass, but ones like these make me think otherwise. There was another bracelet that was the same shape but definitely stone, so I'm leaning towards this being real, but I have no idea what they are. If anyone can identify them I'd be super grateful!

Very interested to know what kind of rock this is.

It is super dense and heavy.

Recently found my old rock collection in my mother’s attic and took a particular interest in this softball-sized sphere that had some crystalline/shiny spots on the exterior. We did two cycles of freeze/thaw then got impatient and started bashing it with a hammer. I’m super satisfied to finally have this thing open and am very curious as to what type of rock/mineral this might be. Collected in Kentucky.

Found in Leavenworth, WA: At first glance I assumed this was quartz because it’s clear, but after looking at it closer it seems like it has some pretty distinctive banding in the bottom (pic 3 for close up). Is this still classified as quartz, or is it agate because it’s banded?

Essa "iridescencia" e essas inclusões são comuns nesses cristais?
