rock and minerals

Hello everyone, I discovered this awesome find in a dry river bed near Faribault Minnesota. I believe there are three possibilities for what this rock is. I believe it is either a large agate, banded jasper, or a banded iron formation. What else could this mystery rock be? I’m new to this...

Heavy hard rock dulls a file quickly, oxidized but not magnetic

Looking at this specimen found in the Mississippi in MN it appears to have mineralized and turned to rock. Heavy for the size, also appears it’s hollowed from what I could see through one slit in the middle. Also wondering what the black staining is?

When a light is shined through it, it has a very clear yellow color and ALOT of air bubbles.

Any idea what they are. They are lightweight.

It's quite similar to quartz, it kind of looks like salt crystals, it's greyish, all of them are almost triangular with sharp edges. it is on an glittery white gray stone with some lighter strips, around the crystals it is more white (maybe calcite?), like in an amethyst geode. I found it near...

Hey everyone, Hoping ya'll can help me understand the difference between a meteorite and natural iron. I doubt that I'm lucky enough to have found an actual meteorite but how does one tell without being able to cut it in half to look at the internal structure? I've attached images of a "rock"...

Hi all you geology sleuths:) I found this on a beach in New Zealand. It is lighter than stone, it is rock hard, and does not have any residue that transfers to material when rubbed. It does not make marks on anything except unfinished porcelain, it makes a dark brown line when drawn across it...

I would appreciate the help identifying it thanks!!! And as always keep hunting!

Found in Hayden, Colorado at an excavation company's yard. Could've been brought back to our yard from Arizona as well because we've worked around the western US (mostly Co and AZ) since 1944. Not magnetic. Does not leave a mark on white paper. Very light weight for its size. One side looks...

I have read as much as I could and looked at every image on the internet...and yet I'm still not confident if these are diamonds. Why? Because for every precious gemstone, there are 10 other stones that look exactly the same. 😂 I know kimberlite, blue ground, natural erosion of diamonds...

I found this around a friends property in central North Carolina. It looks like its containing gold but ive never seen a host rock like in the picture. I've done some tests and know it's not magnetic. I'm wondering if anyone else has an idea of what it might be or way to identify. Obviously it...

Hello! I found this rock in Cooperstown, New York. It doesn't worth anything probably but I am curious what kind of rock it is? It looks like a snake skin/ reptile skin. I found something on Google about the snakeskin agate but my stone doesn't look really like that. Thank you!
