Who's done that ?

Looks very promising!

Just finished another test... I found out that decreasing the decay distance actually works a lot better than increasing it. Now running a render with even less DD.

Below a few version of one render saved in exr.
The first is made a lot darker by decreasing exposure to show what it would look like without water transparency.
The second has a little levels adjustment and shows what the original render looks like, but only a bit lighter.
The last one has extra high exposure and shows what actually goes on in the dark depths of this stone.

I was very happy with the result and will probably finish this project after the next render. (I still have a parted sea that needs some people to save...  )

And here is the last one.
Rendered at 1 detail (the others were at 0.5), and just a few small tweaks. Adjusted levels and exposure of the exr in post.
I'm very happy with the result, which shows a very crude form of SSS is definitely possible, and it can even look like the preview images posted earlier.

For those who want to take a look, the tgd is also attached.

Interesting results. I tried playing with the water shader by itself using a high volume with a nice icey blue color tone but after waiting for the long water shader render times i just gave up.

These renders didn't take so long, though they were over-night renders. Since the planet was a bit smaller but still a planet relatively far from the camera the render times dropped. Orbital or planetary shots always render faster than detailed 'on the ground' shots.

Thanks Mohawk.  This looks like Play-Do.
