stone inspired

i came across these photos on the obumex site. they design some pretty incredible high end kitchens, using beautiful finishes, completely customized, and fit with a world renowned design team. all this leading me to believe that this gravely, natural, sensationally stony substance is probably tough to acquire. it stopped my scroll dead in it’s tracks. i’m crazy about it in a kitchen, also think it could be unstoppable in a bathroom. Anybody have any insight into exactly what this finish is?
