I assumed obsidian, bc of the jet black color. It was glass like and sharp, too. But I don't really know anything. Didn't know obsidian could be clear if that's what it is!
I found this glassy rock at Golden Gardens today; it has several crystal-like hard edges like cuts. Some other rocks seem imbedded, maybe some mica too? Some of it it quite transparent, some is like shattered glass inside. It’s hard to capture in pictures.
I bought this from a collector who said it was hematoid quartz. I’ve seen similar pieces online labeled as “chocolate calcite specimens”. I don’t know the locality. The rust-color comes off on my fingers if I really have my fingers rubbing against it, like a light powder. The bottom sort of looks like calcite. I tried looking on Mindat for any info on this but I can’t find anything.
What is it specifically? Please help. It’s one of my favorites in my collection.
I found this mineral(maybe?) in the dirt while I was pulling weeds. I thought at first it was a piece of glass. But when I rinsed it off, it looks more natural than man made. Does anyone have any clues what it maybe? I am located on middle Tennessee. Thank you in advance.
Does anyone know why this rock would look this way? I found it in Colorado mountains.
Anyone info on any would be greatly appreciated 🤔🫡
I have found several tiny chips of this in the same general area before, but this is the first significant chunk I’ve come across. It has some similarities to our local variolitic basalt (colloquially known as “turtle rocks” around here) and was found on a stretch of beach that yields many of them. But the formation is much more compartmentalized, frothy in spots, and seems to contain some quartz as well. Approximate dimensions: 2 x 1 5/8 x 1 in.
The smaller rock was found in Green River, Utah (desert). It feels almost plastic in texture and a key doesn't scratch it.
The second was found in a rock pile left by a past resident of my house. I don't think it comes from around here, though (PNW). Also doesn't scratch with a key. It has lots of layers and pits and "cracks".
Thank you!
It is heavy relative to its size, hard and solid, doesnt chip away, but pretty smooth most of the way around almost like its been water polished. There is zero translucency except for a small spot on the end of the rock.
Found this bad boy in South eastern Kansas.
My dad and I always joke about finding fossilized poop but this one actually caught our eye.
It was in my uncles rock bed near his porch, but most of his rock came from his property so im confident its origin is within a mile or so of where we actually found it.
Found along the shores of Shuswap lake,
I've been beach-combing for years and never seen a rock similar to this one.
Any help in ID'ing would be greatly appreciated!
i’m very curious about this rock as it almost looks like some form of crystal is coming through it. Can’t find any other rocks that look similar and when I try to Google image search, nothing comes up for it.
Got this from a thrift store years ago. Originally thought it was man made. Now I’m wondering if it’s natural opal. What do you think?
I'm trying to start a garden in my backyard, but everywhere I dig, I'm running into this! It's an interesting blue/gray color surrounded by red clay. Hitting it with something sharp chips it pretty easily and some of the smaller pieces you can crumble in your hand. First pic is in the ground, second is a freshly washed chunk with a small chip. Wondering how deep it might go and if it's worth trying to dig up or through. There's at least a solid 2' x 3' piece where I'm digging now.
Found at a thrift store, 50 in my currency is around 10 USD
Went up to Door County, Wisconsin this week (specifically Ephraim, WI). On the left are Yooperstones that I purchased (trust me, I wanted to find them organically but was having no luck), and on the right are some mystery stones that we found in a random gravel pit near the motel. As far as I can tell, one is a favosite fossil based on the honeycomb pattern, and the other just seems like a random piece of gravel. What would cause both rocks on the right to glow such vibrant yellow? I did wash them when we got home to rule out foreign material like paint (combination of soap, diluted vinegar, and hot water).
Thanks for your help!

I found this rock on the side of a railroad in Colorado at about 7,500 elevation. One half of it looks like all the other gravel surrounding it, while the other looks like Jade. I tried scratching it with a metal knife I believe to be steel and it dulled the tip of the knife and didn't make a mark on the rock. I think it's really special looking and have no idea what it is! Does anyone know?
Found this on the shores of Lake Michegan, but I have no clue what type of rock it is. Pictures of the rock both when its wet and dry.
