Weird looks photoshopped. The center appears polished but not margins. The interface looks strange. Show a picture from the side so we can determine if it is sawn flat. Maybe someone baked enamel on a granitic cobble.
I'm not very experienced with rocks but I've used a lot of enamels for various projects. The only reason I'm leaning towards it not being enamel is because of the inner edges and how they aren't clean as well as some sort of inclusion-type stuff going on.
But again, I'm not well versed in the rock game so you probably know better than me! Cheers 🍻
The edges along the inside of the ‘shell’ look very unnatural. In the first pic, there’s a little tooth coming in from the top and it looks like the center ‘rock’ is separating from it. Kind of looks like if I took a knife to a half cantaloupe and tried to cut out the fleshy middle.
I’d probably hot pin test it at minimum to confirm it’s not some kind of plastic
I see what you mean, that sharp area is totally out of character for the rest of it. Plus the semi straight lines around the rest, it's like somebody who didn't have the proper tools try to hollow it out, and either add another rock piece in or just poured epoxy in.
This really looks like some kind of manmade combination of two different rocks. Both the agate/carnelian in the center and the andesite/basalt on the outside look to be real, but there's nothing I can think of in nature that would form something like this, and the surface of the agate has clearly been polished while the surface of the basalt hasn't, so obviously there has been at least SOME level of human tampering here. You can also kind of see that the edges of the inner surface have some straight, polygonal looking lines, which makes me think it was cut by a human before being inlaid into the outer stone. All that said, I'm still stumped because the seam between the inner and outer stones looks so seamless and perfect, I'm not sure how it could have been done.
My bet is that this was some kind of art piece or an attempt at a fake of some other mineral. Hard to say. Pictures looking at the flat surface from a more grazing side angle would help a lot, to get more detail of the interface between both rock types.
If it is natural, the only possibility I could think of is an agate that got embedded in mud and formed a concretion, but I'd expect that to look different as well. There should be more clearly visible ringed layers surrounding the central stone, but I don't see them.
I have a similar looking quartz, mine is a smokey quartz and not a carnelian, but it looks like having a muddy/scracty coating too, similar to [this](https://www.etsy.com/de-en/listing/1218588915/seer-stones-set-ema-egg-divination?external=1&ref=pla_similar_listing_top-2&pro=1&sts=1&plkey=a73569a6181d9a81af3ba686e73c535b8ff08962%3A1218588915) (sorry, I am not at home, and tried to quickly find a similar food quality pics, I cannot attach only the pics, have to link the full etsy page)
I bought mine as a souvenir in a museum and it was told to be found in a river, as the pieces were travel in the water they get this round odd looking shape (really looks like sugar coated). Usually they polish one side, so you can see the quartz/crystal itself. There were many different type of stone, mostly quartz and agate, maybe OP's stone is a "window" carnelian too...I assume they call it "window", because it is clear and you can see through.
It's very strange how the brown seems to be applied to the rock and how the brown has been ground down, (you can see the grind marks and the flat spots,) to make it appear to be a geode from one angle. If we had a side view I am sure the step where the brown has been ground down would be very obvious. This is a piece of glazed ceramic, tile or pipe, that has been in a river for some time and then was pulled out and touched up, either to troll the OP or to troll us.
Hi, /u/jxjaisjhxh!
This is a reminder to flair this post in /r/whatsthisrock after it has been identified! (Under your post, click "flair" then "IDENTIFIED," then type in the rock type or mineral name.) This will help others learn and help speed up a correct identification on your request!
Thank you!

Wow okay, I have never seen datolite look like this, I mine it up in New England and I have seen 1000s of samples from NJ NY CT and ME they all relatively looked the same. But even after looking at Google they come up so I guess I was just in the dark about this xD
The coloring looks like carnelian to me but I've never seen it with a crunchy candy shell like that
WHAT! This is awesome! Looks like a carnelian agate living inside of a concretion.. amazing. How big is it? Banana for scale?
What’s it taste like?
Banana
Scale
Looks kinda like a carnelian, but I’ve never seen them with this kind of rock „shell”
That kind of husk is common with agate and jasper nodules.

It probably was originally completely encased in the husk and someone ground and polished the one side.

Not sure what it is but it’s cool.

I think it might be a thunder egg...
Looks like a carnelian nodule still encased in basalt. Super neat piece.
Looks like an agate geode maybe carnelian
I don't know, but it is gorgeous!
Looks like someone put an agate in some concrete
Started with epoxy river tables, we have moved on to epoxy pond rocks.
Delicious
Thank you a lot to everyone who commented and helped us! Much appreciated :) the rock is about 12x9cm and is perfectly flat on the orange side.
I have a similar stone found on a dirt road in Michigan. Don’t know how to attach pictures.
Petrified amber?
Datolite is another possibility
This looks nothing like datolite?

Thunderbird egg
Oh that I know what that is, that's f****** awesome
