Anyone know what type of rock this is?

I found this in a small pile of rocks placed on a large boulder, some other interesting materials there as well, so thinking maybe a donation pile? I know I probably shouldn’t have taken it but couldn’t help myself. I’ve never seen anything like it, so would love to know what it is.

First off, where are you ?

Do you find other pieces if that stuff elsewhere in your area ?

Eastern mass. Never seen anything like it.

It's a igneous rock in the granitic family, the orange sections are the mineral feldspar....

Looks similar to this stone I have except mine is a lot more eroded.
