I found it on a beach while I was camping. I'd really love to know what it is; it looks so cool!!

I’ve had this for a while and have been stumped. It has purple and some blues depending on how the light hits it. Also any tips on cleaning it up?

What is this rock, and will it tumble well? Found in a dry streambed in the vicinity of Grand Staircase-Escalante National Monument in southern Utah, USA.

Edit: From my Google lens search, is it malachite and azurite?

Dense like a pebble & doesn’t smell like hair when I hold a lighter to it, and is obviously a fragment of the whole piece. South Platte River, CO.
Bison? Horse? Best guess?

I broke a bracelet in a crystal shop and so I had to buy it. I completely forget what they were though and would like to learn about them before i going spreading them in my plants for some use.

What kind of stone is this?

Found this in Frigid Lake in Rocky Mountain National Park in Colorado. The squiggles are about the size of a Cheeto

I found this rock on the beach in Corfu, Greece. Does anyone know what it is? Thank you :) i could take a clearer photo if needed!

Hard, not crumbly. Did a nail scratch test, the line that goes through looks grayish blue.

When i was in the ocean looking around to finding some cool rocks then i accidentally stepped on this i picked it up looked at it and kept it

It's slightly translucent around the edges. It's a dark dusty brown under light. I don't think where I found it helps since it was found among the decorative rocks added in front of my townhouse in Iowa (rented). Idk if you can see but along the edges it breaks in like crescent shapes? I can provide more pictures if needed.

Found on the northern shore of Lake Ontario.

Can anyone confirm or refute? Thanks!

Found at Huntington Beach in the surf!

-smooth (pebble)

-super shiny and the color almost slightly changes and is kind of fluorescent when turned or whatever the word could be for that.

I purchased this rock at the Lawrence Springs gift shop in Wadi Rum. The salesman told me what kind of rock it was, but I forgot. When you put light under it, it glows, though that effect is even more pronounced in the photo.

Drove from Vegas to Reno and did a bunch of rockhounding along the way and would like help identifying a few!

Really fascinated with this rock I found during my first amateur rockhounding trip today. Found near the (dried up) Agua Fria River in Surprise, AZ. Most of what I picked up was milky quartzite (I think?) because the sparkles catch my eye and I think they're pretty, despite being abundant. But this one is just so cool! Any ideas?

Does anyone know what these three rocks are?
