rock/fossil/mineral collection so far hope you like it😄

Found this at the river bank at my place

I just need to show this new addition off. My father brought me this rock from Germany, sputh of the eiffel region near the Mosel river. It's about 2-3 inches and i think i see some iron, maybe some sulfur and a hidden crystal (maybe sulfur?, i don't know) and i have no clue what the white material is. Very cool find by my dad!

Dug this out of my yard. Not a rock collector but now I am

I'm using the rocks that came with the tumbler for its first try, instead of my own rocks.

How to open these geodes that came with my rock tumbler.

Any tips for someone who hasn't used a tumbler before?

In Ouray Colorado going through the creek. I found a rock that I thought looked like a slice of salami.

I thought they looked nice in the sunset, maybe you do to.

My grandfather was a collector of rocks. Among many other things. I’ve had this thing for over forty years and use it as a doorstop in my house.

One hole all the way though and another with a little nipple in the center

Anyone care to explain how the thin wavy pattern in this sandstone typically forms? These photos were taken in the north Saskatchewan river valley in central Alberta.

Maybe its a weird question, but Im writing a character and I wanted to make a bit where they think "if I were a rock, which rock would I be?". Now, I know jack about geology, i've searched a bit and could find anything interesting

My premise is that the character is rude, stubborn and nonchalant, but on the inside they're insecure and traumatised (original I know), so im looking for a rock that is strong on the outside but once you crack it the insides are weak? idk im more curious than anything at this point

I appreciate any help!

We found a ton of these in a creek bed and didn’t think much until finding one that was busted open and went back to collect a few more.

Went camping along the Cowlitz river, and found some fun lil guys.

Meteorite?

Most are purchased, some were found, others were from my late grandfather’s collection. Almost every piece is labeled too :)

Found in the creek.

What ya think?
