r/RockIdentification

Found central Alberta, Canada

Favorite one I ever found. Doesn't change really when wet.

Southern Ontario

Found near erieau ontario. Just curious if I found what I think I found!

Found this along a rock wall along the side of my house. The wall has been there for 40-50 years. It’s different than all the others his small wall was built with.

the seller i bought from in a store wasn’t sure what the blue and green stones were, but she said the black ones were black tourmaline but i’m not sure if it is

i have a feeling the blue mineral is kyanite but i wanted to ask here first

i also have no real clue what the green one is. i took pics inside and outside in daylight

the seller also had no clue on locations for any of them 😊

thank you for the help!

Been looking at this rock for a while thinking I should cut the end off or something to see if it contains crystalline structure inside. Anyone think it’s worth it? Picture doesn’t do it justice, the top and other darker areas look purple (it’s dry). And it’s very smooth compared to other areas of the rock.

It feels heavy for its size, hard to see on camera but it has very small glimmering blue bits. I may have added to many images, last 2 have a cassette tape for scale

Sorry for the photo quality, it's the best I could do.

I got these three guys about a year ago and I still i’m not sure what they are exactly. Do you guys have any ideas?

It’s super hard, cold to the touch. I thought it was obsidian but the colors and little crystal pockets don’t really align with that

I dug a lot of holes for fun but like in 1 spot I found a bunch of black rocks. The smooth one is weird because it's harder than quartz but the other ones aren't.

Was outside re-potting plants and noticed this in our landscaping rocks (please ignore the dirty nails, hadn't scrubbed them yet) and the majority of the rocks are just generally light colored, basic rocks. I'm a geology 101 gal (I watched Nick Zentner's zoom class lol) so I'm just curious to know if there's anything extra special about it, or if anyone can further explain exactly what I'm looking at. TIA!

Hi, I found this stone in a field yesterday. Does anyone know what it might be?

First post on this sub.
Any feedback is appreciated😊

My son thought it may be a metal. If it is, it's not magnetic.

Doesn't remember where he found it.
We live in the PNW, but it could've come from anywhere.

We want to try to split it open, but we don't want to until we know a little more first.

Thanks!

Found in northern california, La Porte area on a gold claim

Any ideas?

Found in Denver. To me it looks like a siltstone.

Found in SW Mo creek. Any ideas?
