This is a very nice desk!  Not sure why they say 'marble', there is no marble or marbling design on the desk itself.  But the overall quality is very good and we would recommend this desk!  My husband put it together pretty quickly and was surprised at the weight of it.  
The packaging could have been better - The first one arrived damaged.  Had to wait another three weeks for the replacement, which was quite inconvenient.  Overall, pleased with the desk, though.
