Not sure about the smaller cube, it makes for strange refractions and reflections that I personally haven't seen in emerald cut gems. Check out this reference diagram to see how the "step cut" effect happens.

You're on the right track with the mia_material_x. I probably wouldn't use a marble texture as it's making the gem appear kind of cloudy. If anything, since the camera is so close, I'd maybe use a modified solid fractal texture (high amplitude, high threshold etc) in the bump channel to create tiny imperfections. If you're going for realism then there is work to be done with the lighting and environment as well. Lots of studio lighting tuts floating around.

You can just assign a new material, and the old one will no longer be applied. Or you can right click on the attribute and "break connection" and then apply a new texture. Or in the hypershade you can select the marble texture and hit delete. If you want to clear out unused textures, in the hypershade you can go edit > Delete unused nodes.

Since you can't upload the environment texture, could you show a render of your current results?
