Here's what I was using - curious to see what this looks like on your lamp:

// SSLT Units
#declare SSLT_UNIT_CM = 10;
#declare SSLT_UNIT_M  = 10 * 100;
#declare SSLT_UNIT_IN = 10 * 2.54;
#declare SSLT_UNIT_FT = 10 * 2.54 * 12;
#declare SSLT_UNIT_YD = 10 * 2.54 * 12 * 3;

#declare SSLT_Samples = <16, 8>*8;

global_settings {
   assumed_gamma 1
   mm_per_unit SSLT_UNIT_CM*10
   subsurface { samples SSLT_Samples.x, SSLT_Samples.y }
}

#include "rhino.inc"  // the model is 1 POV-unit long

object { Rhino
   texture {
      pigment { rgb 1 transmit 0.1 }
      finish {
         // ivory?
         subsurface { <0.70, 0.72, 0.57>, <0.000314, 0.00049, 0.00067> }
      }
   }
   texture {
      pigment { srgb<235,220,190>/255 filter 0.6 }
      normal { agate 0.1 scale 0.15 }
      finish {
         specular 0.7 roughness 0.01
         reflection { 0.05, 0.95 fresnel } conserve_energy
      }
   }
   interior { ior 1.54 }
}

Cheers,
Rob
