Found in Baja California Sur, México. Heavy, hard, around 1inch, not magnetic, has small pieces of stone inside. looks goldenish irl.

Found this rock on Lake Michigan beach. The host rock appears to be quartz. I feel the reddish areas look more like jasper. I’m very curious about what looks to me like white microbanding and the weird shapes pattern. Is this a fossil soup that has agatized? Appreciate any help in explaining if it’s an agate and why patterns are so odd.

Obtained at a yard sale years ago, no information given. NWI/USA. Large and heavy, white/gray flakes on hand when handled. Initially i thought the red/brown was just dirt/matrix, but those parts have a defined structure and are shiny like a crystal.

These pics are dry, have not gotten it wet. Overhead indoor light, plus phone flash on some pics.

Thanks!

I found this in spring along the shores of lake superior. Could this be flow banded rhyolite? Pictured dry and wet under led light

I found this rock in my attic, but I don't know where it originally came from. Probably Slovenia.

It's about the size of a fist and surprisingly lightweight, almost like a piece of wood. It has black, glassy-looking areas and translucent yellowish or honey-colored pieces. The rock is quite crumbly, and the white areas visible in the photos are just freshly broken surfaces. Some of the smaller fragments are slightly translucent.

So, my mom found this rock ca 50 years ago behind her parents house (ca in the middle of germany). It is ca the sice of my hand. She took it home after my grandmas death and was wondering what it is. I appretiate any help.

Found while emptying my aquarium. It could be aquarium gravel but a lot of the mix was collected on an island on Lake Nipissing in North Bay, Ontario. The green looks so out of place but it only seems to be on the surface. It isn't paint or anything, I think?

I found these rocks at an estate sale. I just thought they were pretty so I picked these but I'd like to know what I'm looking at lol

Google images keeps telling me it’s a fossil but not so sure. I just figured it was some type of agate in chert possibly. Already took a dremel to it to smooth it out so I don’t have before pics but the agatized part was already as dramatic before I worked on it. Found on Long Island New York.

Very smooth, lightly pitted, lightweight and found on a beach in RI on the east coast. Is it just a cool rock or something more?

Found on Lake Huron shoreline. The pattern of dots is throwing me off. Any help appreciated. Thanks.

The black mineral comes across as being too brittle to be biotite, and is not flexible whatsoever. There are some rust-colored spots on it.

Found at west coast(Sunnmøre) of Norway.
Suspect mohs between 8-9. Don’t feel like I’m able to leave any marks with an 8 pick, but 9 definetally do.
All pictures dry
Colorless and pink/purple

Found this in a creek by my house. They said it was leftover from Mason jar production, but I'm not sure. Any ideas on what it could be if it's not?

Dry and wet rock in the pictures.

Found in western ozark creek bed. I know first pic is silica of some kind. Second pic is brittle
Fragile material black with some shiny white vein, it smells strongly of sulphur and is quite heavy for its size and show signs of rusting.

It's an erratic from NY. I think it's granite, but I'm curious if it's a rock type ive never heard of.

It's metallic (metal detector).

This is a black flaky metallic-looking mineralo alongside green garnet (as is hopefully visible in some of the photos) and a white mineral that looks like calcite. Attached is a photo of the streak on the bottom of a ceramic mug. The metallic mineral is extremely delicate and brittle, and will break into shiny, thin sheets at the slightest touch. It has some small rust-colored dots on it as well.

I’ve searched online and got many answers; quartz, jade, howlite, etc.. please help me identify!✨
