I think this is a perfect alternative to all the preceding!

The basic pigment_pattern used for the mineral grains as well as for the 
mask controlling the size distribution through the rock, is crackle 
solid. It has the advantage to well-discriminate between the different 
minerals, better than all the previous experiments. I found this out by 
examining a couple of traditional POV-Ray stone textures, more 
especially T_Stone_28.inc, and tweak from there before substituting the 
results here.

I think that the "blurry" aspect that Mr was complaining about, came in 
fact from the size distribution within the mask pattern. It may still 
exist a bit, but I developed a mask with less diffuse transitions.
