Suppose the center inlay WAS identically the same on both ovbvese/reverse sides of the chip? Would you consider turning the chip over so that the Edge Inserts on one side in view would be different than the other side? In other words; if one chip side had 3 sets of White/Black SxS inserts showing... wouldn't the other side's inserts be 3 sets of Black/White SxS inserts ... constituting two variations of the same center inlay using your logic?
