Decided to use the one in shapes2.inc and just scale it, thought that 
means, at some point, lopping edges off and replacing them with 
cylinders, etc, to round it. Got a different problem though. The 
texture... So far I have this, which I am not real satisfied with:

texture {
  pigment {marble
  turbulence 0.85
  color_map {
    [0.00 0.40 color rgb <0.66275,0.57647,0.58824>
               color rgb <0.65882,0.56078,0.57255>]
    [0.40 0.72 color rgb <0.64275,0.55647,0.56824>
               color rgb <0.63882,0.54078,0.55255>]
    [0.72 0.95 color rgb <0.62275,0.53647,0.54824>
               color rgb <0.61882,0.52078,0.53255>]
    [0.95 1.00 color rgb <0.57775,0.49147,0.50324>
               color rgb <0.57382,0.47578,0.48755>]       
  }
}

What I am trying to do is duplicate the colors in this:

but looking more like:

Though, in fact, I plan to use "both" color sets for different parts of 
the item I am building. And, since this is going to be a *large* object, 
I want to make at least one band in it so that, instead of having the 
reflective qualities of polished stone, it has granular crystal like 
veins, which have a metallic finish. So, what I am looking for is 
something like:

texture {
  pigment {marble
  turbulence 0.85
  color_map {
    [0.00 0.40 color rgb <0.66275,0.57647,0.58824>
               color rgb <0.65882,0.56078,0.57255>]
    [0.40 0.72 color rgb <0.64275,0.55647,0.56824>
               color rgb <0.63882,0.54078,0.55255>]
    [0.72 0.95 color rgb <0.62275,0.53647,0.54824>
               color rgb <0.61882,0.52078,0.53255>]
    [0.95 1.00 color rgbt <1,1,1>
               color rgbt <1,1,1>]
  }
  finish { stuff to make it polished stone }
}
texture {
  pigment {marble
  turbulence 0.85
  crinkle
  color_map {
    [0.00 0.95 color rgb <1,1,1>
               color rgb <1,1,1>]
    //Darkened to enhance the vein like appearance.
    [0.95 1.00 color rgb <0.47775,0.39147,0.40324>
               color rgb <0.47382,0.37578,0.38755>]
  }
  finish { stuff to make it metallic }
}

Right? Can just try it, but wouldn't mind some input on how to get the 
texture itself a bit closer to what I want as well.
