Looks a lot like the tile I have in my bathroom and laundry room. Casa Dolce Casa 'velvet' in the charcoal color. I'm including the link to the product website. But I don't think it is a great representation of the color. Mine has much more brown (with black). But the color on the website looks more white with black.
Here is a link that might be useful: Tile
Thanks! Where did you get yours? If there is a store locator in the US on that website, I can't read it.
I got it at a local tile store in Orange County, California.
