Recreating a specific marble statue color mix

[Galloway]

Hi all-

 

I'd like to try and paint up the statues on my Darkshroud the same way as in the picture linked below (not sure how to embed directly in post), but I'm not really quite sure what colors/paints/washes and order to use. I've found plenty of great marble and stone tutorials out there, just nothing that seems to give this mix of colors. I'd guess some build of darker to lighter bluish greys with a dark wash in there, followed by light grey final highlights, but not sure if that's right. Any suggestions/advice greatly appreciated.

Looks like the base layers are flat  dark grey, then the Temple Guard Blue - Aethermatic Blue - Skink Blue spectrum.
