I would suggest a bozo pigment of varying greys scaled down really small.  If
this doesn't work quite well, then I would suggest trying to add a bozo normal
that is too scalled small.

try this:

texture
       {
       pigment{ bozo color_map{[0 rgb 0.6][0.3 rgb 0.4][0.7 rgb 0.7][1 rgb 0.6]}
scale 0.01}
       normal{bozo 0.1 scale 0.01}
       }
