So let me get this straight... you're saying that you don't even know if the smooth stone used in the castle was actually marble, and not just garden-variety smooth stone? I thought as much. Especially since marble is never a solid colour, as it is seen to be in the castle, with marble shown to have swirls and discolorations. (Marble is like diamonds - you'll never find a perfect cut.)
