Hand modelled clean geometry, i did not use any booleans, mesh smooths,displacement maps or even bump maps. Everything in the model is actual geometry. every little detail in the model is ahieved through vertex/edge/face manipulating. I modelled it to use in my own gi projects.

this is not a low poly solution, I took visual quality in higher regard against poly count.

The model comes with a raytrace marble material but I also included a vray marble material that will help you in your renders I hope.
