These are priced by weight and not necessarily by size. I would have to say the Black Agate is my personal favorite of all of the black stones. It's probably because some of them have a bit of design in them. Not all of them do, some are just black. If you have a preference, you are always welcome to message be with your order and I will accommodate if possible.
