I am going with a similar look and am doing a carrara & nero marble basketweave faux rug for the floor. I will probably have darker bardiglio tiles around the edges of the room and there will be a cararra twisted rope border (and nero liner tiles on each side of the rope) to delineate the "rug". This way, the pattern does not overwhelm the room and it is a very pretty look in and of itself. I wish I had a mock up of it because even dh has not seen what I chose (other than the basketweave middle), lol. Oh... and am using dark gray grout because white would be just plain suicidal in our house. Maybe Bill V has done similar and has a pic?

Mine is venatino. I was told they come from the same quarry but are classified by appearance. The background of the venatino is whiter where the background of carrera is more grey. My slab has a mix of spots and finer dark veins with some more subtle broader ones. They reminded me of ink squiggles and blots on old parchment. I thought of da Vinci and I was sold. And in the end, that's really what matters -- finding a look that is special to you. No one else may see my marble the way it hit me.

I don't think you're going to get the non organic look of Ceasarstone to work with the organic look of the marble, irrespective of the color undertones of each. If you want marble flooring, why not marble countertops? Or, if you want Ceasarstone countertops, why not use the Ceasarstone tile for your flooring also? Have you experimented with samples of the marble you're considering? Marble floors will looked lived in and worn in no time in a kitchen, so be sure you're OK with that look.

It reminds me of when I was renovating my condo back in 2010. I had seen some gorgeous crema marfil subway tiles for my guest bathroom that I was all set to pull the plug on. Well one day I went to a different tile place to get something for the floor of that bathroom and she pulled out the same crema marfil tiles from the same company. Instead of being barely beige (almost a white color), these were dark beige and not at all what I was expecting. Apparently I learned that day that because it's a natural stone, there is no chance of being assured of what you'll get.
