Crand, indeed, is not recommended, especially for animations, and imo it 
doesn't look realy right.
I would try a very fine granite normal, associated, for example, to the sand 
texture in isocacti.pov (one of the standard POV-Ray scenes). And then play 
with the bump_size and other parameters to get it right.
