The plus: the marble is real, the gold base is metal not plastic and it is a sturdy, quality looking piece. 
The minus: as a few other reviews have said (which I should have listened to), the metal piece at the harp top is actually cut incorrectly so the shade will not lie even. Once the shade doesn’t lie even neither will the cap at the top of the lamp. 
I am going to return and request a replacement one time in the hopes it will be made correctly.
