Alan, At this point in time I do not have this marble in hand. But from what I remember there might not of been a noticeable seam. Not to say there was one or not. I guess Lizzy would be the one to answer that one. She knows so much more about seams and such than I do. But I really thank you for your observations on this marble it is greatly appreciated. The photos that Lizzy took pretty much show the whole marble
