I feel the same way I think it's just carrara marble in hex.

The green seems to be reflecting off the tile.

If you look at the second picture you see gray and white.

Totally agree now that you guys pointed it out!

Is it the same tile in both of the photos? The top one looks like a 1" Calacatta hex and the bottom looks like a 2" Carrara hex.

Also - looking at the bathtub details - I don't think they're the same room.

they both look like carrara, the top one is getting the greenish hue from the wall.

here's the calacatta gold
