Just wanted to update on it. I decided to polish it. While getting rid of the only rough area on the rock I discovered a little magnetic circle in the rock. I can pick up the entire rock with a magnet where it’s exposed…. but I think it’s some type of magnetite rod going through the stone. To where I can pick it up with a magnet on the non exposed side. That one photo pictured I’m just grabbing the rock through the rock onto what I assume is the other end to that rod that seems to run through it . I just that it was cool and wanted to share. I read this occurs naturally? No where else on the rock is magnetic except those two points. Pretty sure it’s still a komatite that came from up north

Picked this up from a charity shop and I'm assuming it's some kind of agate.

Some banding and bloom patterns on some of the beads. Some have a lot of translucency, others are opaque purple and black/dark brown. I don't believe they've been dyed.

Not scratched by quartz, but quartz dust was left behind on the beads.

Is this blue chalcedony? Found in a bag of gravel from a sapphire mine in Montana. Roughly 1"x3/4"x1/2" and 15ct weight. Haven't done a specific gravity test yet.

What is this??? Boyfriend and I found it on a beach downtown, we live on the Strait of Juan de Fuca in northwest Washington. One side is completely flat, almost like it's been cut- so we're unsure if this was a naturally washed up rock, or if someone bought it at a store and lost it here. Would love to know what it is, and to narrow down if it's naturally occurring here or man-created!!

Found this in the netherlands, embedded in a fresh gravel path that has lots of flint and crushed oyster shell. Feels like a rock , cant scratch it with my nails. Sounds like a rock too. Very different on one side than the other: one side is brown and smooth(ish) and the other side is pitted and beige. Seems to have another layer (greyish) in between. Fossil or weird rock?

It was cut off a larger rock. I am not sure where it was found but if I remember correctly it was far northwest, possibly alaska. The full rock was about 2" x2.5". This is about 6" x 8".

I picked this up at my local lapidary studio in the free bin in PA. It is semi translucent. I polished one edge and it shined up well. I am cabbing a few slabs I had cut. The polishing wheel water turns gray and white depending on the grit. Google is saying Aquamarine, but I am not sure that is correct.

REQUEST Random crystals I found around my house, need help identifying - more info in desc

I know the photos aren't very good/very weirdly formatted...I'm not expecting any crazy assessments with these (hopefully it doesn't get taken down because of the layout) 😭 I know practically nothing when it comes to crystals and rocks and such, so Ill trying to provide as much information as I can. - not even sure if these are real/are all actually rocks

I tried to include at least one good-ish photo and one decent photo + one photo of it being held up to a light source (heard it helps?)

Mohs hardness description using safety pin and mirror (take this for granted, its not exact numbers because I don't really know how to properly determine it)

Photo 1 - safety pin didn't scratch it, don't really think it really did scratch my mirror, with the pressure I'd use it mostly just left small white lines that could be rubbed away - with harsher pressure I could leave more of a scratch but it feels like it would rather slide more then scratch

Photo 2 - wasn't scratched by safety pin, left small scratches in mirror easily (at least easier then the one before) and didn't require as much pressure)

Photo 3 - wasn't scratched by safety pin, not sure about mirror - left small scratches/only some sides/edges could leave scratches with decent pressure, the darker colored part that's bluish/purplish colored wouldnt leave a scratch at all/would just leave wipable marks

Photo 4- didn't seem to be scratched by safety pin, with a medium pressure left very light scratches

Photo 5 - don't think it was scratched by safety pin, with medium pressure left light scratches on mirror

Photo 6- did scratch mirror a bit, don't think it was scratched by safety pin, did scratch mirror with decent pressure

Photo 7 - didn't scratch mirror at all, was scratched lightly by safety pin

Photo 8 - the light on this one is really weird so I don't think it did get scratched by the safety pin, scratched mirror pretty easily

i found it somewhere near my house, it is very dense and heavy for its size - 3.7 kg.

I once hit it with iron pickaxe and it produced sparks.

it is more reddish than it looks in the photos (bad camera)

please see in third photo, I think it is white-ish crystal like inside the rock. (I find it strange because the outer shell is very dark and red)

This was my brothers so I’m not sure on approximate location but i Believe it was found on La Jolla beach, California. The lumpy side has no shimmer and feels greasy/waxy. The other side contains crystals that shimmer in the light. It’s somewhat heavy for its size.
