Subtile white marble (so difficult...)

Hello
I have tried to create one's with a wax material base from the library, but I'm really not a master
...
The very subtile transparency/reflection/sparkling is so difficult to achieve!
Some example of my goal (and the wax base, but nothing worked from it...)
Ps : I'm on V2

No answer... I think that it is too simple for you.
I have the V2, and the material editor is not so easy for a guy like me, I saw that in the V3 Maxwell has made a new way to build materials, more intuitive and friendly, like me

By the way, the wizard milk is not a bad starting point. Try to find one good image reference to work from though, as the transmittance color will vary for different pieces of marble, and from photo to photo.

Thank you Seghier, I just download the "Taj-Mahal" mxm, I will test it tomorrow!
Bograt thank you too, your idea to use sss milk like a base seems to be the trick to do, I will test it!

As per:

You will want to set the Nd to 1.6585 -- if you want to enable dispersion set the Abbe number to 49.91.

For marble? Your a nutter! render times will go through the roof! I also think an IOR of 1.66 might be a bit high... especially if using force Fresnel. Ive had good results at around 1.42
