Nah doesn't spin! The photo is dicieving, I was wrong when I said pin head, I mean like the thickness of a pin lol, it's tiny! Just really zoomed! Wouldn't even think it was a bead at that size.
A friend just looked at it and said probably slag, but it's size is way to small to be a drop I would of thought!
Either way a good peice to look at for years to come.
