Thanks.
I will put the coal-like ball somewhere else on next rendering.

I will give it a try, but I'm not sure of the final effect once on the 
shelf.

The main parameter that controls the carved-mesh-effect it is the
"accuracy" setting. A bigger accuracy setting will close the mesh
and a smaller one will make it more airy.

The attached images shows how it looks in your framework.

Let me know if you'd like it changed in some way (thicker or thinner jade?
Shinier or less? etc)

This is the entire include file I used to fit in your "balls.pov" framework.
=====ball-2x1.inc=====
#include "colors.inc"
#include "textures.inc"
#declare cells_pigment = pigment {
  crackle color_map {[0.0 color rgb 1] [0.3 color rgb 0] [1.0 color rgb 0]}
}
#declare fun_pig = function { pigment {cells_pigment} }
#declare fun_val = function { fun_pig(x,y,z).red }
isosurface {
  function     { .95-fun_val(x,y,z)}
  contained_by { sphere { 0, 1 } }
  accuracy     0.1
  max_gradient 7
  texture {Jade finish {diffuse 1 specular .7 ambient .15}  }
  ball_at (2,1)
}
======================

PS: I think this is the coolest idea for a collaborative project.  The
constraints
      of a unit sphere make for a very nice picture.
