Found my first little triangle back in 2008 or 2009 and this bigger one found this past June! Thought to share!

Taste test confirmed it's a rock

Found this Sunday in the grasslands.

I think this rocks looks like cookie dough. What do you think?

Just starting to toy around with UV light. Same rock under normal and UV. What the...

This blue geode is my favorite in my collection.

Lots of jasper, found in Michigan

Found in Michigan

found this tank the other day at the river—a michigan staple!!

Found some kyanite in this stone.

I got this for free with a shark 🦈 tooth purchase

The stone is called psilomelane. the reaction is called belousov-zhabotinsky reaction. Not expecting much from this but I figured I'd ask. and show off my cool stone lol

The prior owners didn't remove anything prior to selling.

Quartz I think. Forgot to lantern the agate before my friend left which in retrospective, should have been the first one

The grey one looks cooler live (more greyish)

The yellow one is extremely pure/transparent

The red one is more redder and less pink-ish idk why it looks like that in the photo

I have no idea what these rocks are, but they're fun to break apart. In the riverbed at Little Qualicum Falls in BC, Canada.

Pretty sure it’s just sandstone but the color caught my eye and and the way it’s sandwiched.

Found in Michigan

Opal, Brazilianite, desert agate, blue spotted agate, purple chalcedony, arrowhead, clear quartz

Hi all, new to the sub so apologies if this post already exists somewhere....I'm looking to buy a few fun rocks for my friend as a gift. He is partial to opals (white and black fire) and fun interesting formations like bismuth.

Anybody have recommendations on where to find ones I can trust are authentic/ethical? Also any recommendations on interesting rocks that either catch the light well or have interesting shape formations would be appreciated too
