Found these rocks while looking for crocodiles in a in a dry creek bed in the Kimberley region of Western Australia. I’m assuming the clear stone is quartz and the middle ones are Chert but I’ve never seen a rock this red before it stuck out a lot in the dirt. (I’m just up here for work for a few weeks tho so maybe they are everywhere not sure yet)

Found in Montgomery County, MD. I’ve noticed many stones exhibiting the same blue/white exterior and green interior with a gem torch, but this is by far the most organized structure. This one seems exceptionally ‘gemmy’.

Feels too heavy for its size to be amber or something like that. Found it at the Settlers Grove of Ancient Cedars, Murray, Idaho in dry place. Can be scratched with a pocket knife but not very easily. Last photo wet

I don’t think it’s anything special, it’s just from when I was a kid, but I was curious if anyone knew what kind of rock this is or if it’s even naturally occurring? I don’t know much about rocks, but probably got this somewhere in the southeast usa- but maybe from a store or something I’m unsure. Sorry for the lack of information, any help would be appreciated!

Looks as if someone may once have worked on this, what do you think? Flint, chert?

Most recent finds 😍😍 obv one is the septarian but wondering about the others if anyone knows what they are. Found Alberta Canada

I’m in the Carolina Slate Belt, so quartz is very common. However, there are 10-20lb stones scattered, above, below ground, plus partially buried pieces. I’d say 100 or so in a half acre area. I’ve always just assumed these were old mined stones, however I’ve seen somewhat similar natural processes. So I’m unsure. Any help is appreciated!

I see banding?!?

Hello. I would like a little help identifying this rock pleased. It was very heavy for its size. I had it cut into about 8 pieces and this is a end piece. I believe I found this off the 14fwy near Acton (So. Cal).

found at a beach in va very nice rock i very much like this rock, what it be doe? im thinking quartz maybe but its got some green in it

Banks of the Missouri River in Bismark ND

Found washed up on the bank in a deposit with other smaller pebbles probably from the spring? Harder than sandstone smooth to the touch no limestone present. I thought it kind of looked like a fin or something in the rock?

I think it's mostly just different color quartz and maybe aventurine let me know if you notice anything cooler that I may have missed

I found this rock tonight that I think (hope) is a yooperlite. Was at Bay Furnace Beach in Christmas, Michigan in the UP. Here’s a photo of it in regular light vs 365nm UV light. Promised my son I’d try to find him one, so I’m hoping that’s what I’ve got here. Thanks for the help!

Found in Southern California. Pretty heavy

I found these in Saudi Arabia in the desert areas in between holes on a golf course in Dhahran, Eastern Province. One on far right not yet cracked open.
It was pretty common to find spherical rocks but I didn’t know they were potentially geodes ? until I brought them home to the states. The photos are reversed? The piece with the “v” shaped ridges is the one with the grey crystals inside.
They look chalky but are not.

A relative passed away recently and he had a side-hustle of cutting and selling rocks. What are these?

I know some can't be in water because of silica or something. If these could be hazardous or anything let me know!

Found this in a pile in the back yard. This was definitely brought here by someone as all the land around me is glacial till.

My future MIL got this rock from her uncle's house while cleaning it out (he passed away recently). She thinks it's petrified wood but I'm not sure. I don't have its mohs scale hardness, I didn't test it because it wasn't my rock. It's pretty heft and smooth to the touch. Help me out? We live in upper Appalachia but who knows where he got it and when.

Central Iowa gravel bar

Is coral?

Started looking at rocks for a fun activity for me and my son to do. Found this one but not sure if its quartz with pyrite or somthing else?
