[jaroberts28]

So I found a very out of place rock for Minnesota.... Looks to be some kind of quartz or quartzite with like almost emerald colored crystals in it. I am trying to find my camera to take a picture of it. I have yet to do any scratch test or anything. I just wanted to know if anyone has found anything like this before up here and what is it!!! I am not aware of any beryl up here but who knows what is in the glacial till.
