I'm not really surprised using the standard Jade as a base for your 
subsurface texture. Real, expensive jade is very light in colour. The 
lighter the colour the better quality.
I found these values on the internet.
colour rgbft < 0, 0, 0,0.000,0.000>// Jade	
subsurface { < 0.657, 0.786, 0.9>,< 0.00053, 0.00123, 0.0021> } // Jade

Mostly yes. I've been using reflection {
rgb <0.000,0.000,0.000>, rgb <0.100,0.100,0.090>

The image does seem to be missing something. That's a problem with SSLT, 
it is back to the days of slooow renders. :-(
