can anyone identify this rock?

[hunterx1]

hey there everyone, hope you are doin well. i was out in the river behind the house here in wisconsin and i found this odd rock...i have no idea what it would be. the outer shell of it is like a chestnut brown, when i flipped it over, it was already split and the inside of it was....well....strange. as you can see on the pic, the inside of the rock is a cream white/off white...the chestnut brown shell part is only like a 16th of an inch thick surrounding this white. in the very center, there is a small, circular darker red "core" for lack of a better word...it almost looks like a red quartz. would anyone be able to identify this?

I'm not sure what kind of rock it is but it looks interesting if I was you I would let an expert look at it it could have some value to it.
