My take :
Add some pattern to that plane, like granite or bumps scalled smapp.
You can also add some normals. I'd go with granite of agate, maybe bumps 
scalled small.
To really go all the way, you can replace that plane with an isosurface 
using a granite or bumps based function. Here also, you can add some 
pattern to make it more interesting.
