What might be of help, if you can do it, is to simplify the model. Using
a trial version of 3DS Max I reduced the vertex count to 20% of the
original (28 Meg, 9 Meg zipped)

Thanks but it is the bog standard marble. It is backlit and that makes a
difference. :-)
I think I'll try Lucy with the material map I used for the Buddha.

And here it is. I've created another simplified mesh using 10% of the
vertexes (14 Meg zipped to 5 Meg). It messes up my big idea of
mm_per_unit though.
I don't mind sharing it even though 3DS Max says the mesh is a rats nest.

Here's my little attempt. Rendered in 10mins, without aa though. One thing I've
noticed is that I get a large number of bright single-pixel artifacts unless I
use large sample counts (using 1000,100 here), even when also using aa. Is there
any way to avoid this, or is it just the nature of the beast?

Very beautiful texture!

Nice but use aa it makes a difference. My samples are only 100, 50. Back
lighting makes a difference as well.
I used mm_per_unit = 1.105 for the first one and 28.6 for the green one.
It took well over an hour.
Your image looks more like marble what settings did you you use?

Thanks but as I said to Jim it is the marble from the paper.
I like the jade one posted later better.
I'm going to run some more test renders overnight.

I lied, I've just noticed that they are 500, 250

But does it? I thought aa was wasted on otherwise supersampled features like
area lights, focal blur, media etc? The edges of lucy's self-shadows are lovely,
it's just the floor shadow and her horizon that show aliasing. I'll do some aa
tests tonight.

Excellent, I was shooting for a very translucent marble.
mm_per_unit = 80 (the model is about 1 unit high)
samples 1000, 100 (only way I could get rid of bright point artifacts)
subsurface { 5*colour, 0.5*(1-colour) } (IIRC!)
