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.
