Fantastic thread!!! Very excited as I was already a member

i'm assuming this is just a white quartz. What makes it so bizarre is I live in the mountains of western North Carolina and I have nothing but Boulder after Boulder after rock after rock. Some the size of a car. They are all dark colors. This thing stands out from a mile away and I don't know where it came from as it doesn't match anything else in the creek. Anything special about it? I have more pics if needed but I doubt it

Thanks!!
Ps:Hard to tell but it's the size of a football.
