Nothing bizarre about it. It's basic Damascene steel:
Typically this would be simulated using procedural "marble" textures in 3D programs or filter generators like Filterforge. The coloring in the image is probably merely a combination of clever lighting, reflection cards and the inherent qualities of the folded steel layers as they are treated with acids and then polished and rinsed with oil, giving a "thin film" dispersion effect like a soap bubble. Additional treatments like anodizing the steal or temperature regimens that give it a blue sheen could of course be involved, too. in any case, only the original photographer can tell you the details, but it should be easy enough to find info on the web based on my hubbub.
You could make a pattern like this using the Clouds filter,with some sort of Posterization and/or Gradient Map, maybe with a Hard Mix blending mode, maybe a Mask for some Layer Effect?
