A pro suggests on that page that it is a marble mosaic. Seems possible?

I'm not sure what provoked your sarcastic response. My questions remain as to who makes this or a similar tile and where can it be purchased.

I don't believe the previous poster was trying to be sarcastic. People on here are usually helpful.

I think crl assumed you would understand that if it is a marble mosaic, it should be easy to find from various makers/retailers.

Whoa! Definitely not being sarcastic. You titled your thread "stacked stone backsplash." It does not appear to be a stacked stone backsplash to me. And the pro comment on the picture suggests that he or she doesn't think it is a stacked stone backslash either. I was trying, in the nicest way possible, to suggest that you look for marble mosaic rather than "stacked stone."

I googled marble mosaic stacked tile and got a bunch of results. One link below. Can't vouch for the site but it seems to be available.

Here is the Ann Sacks Athens Grey:

Sorry for taking offense crl__, my bad. I appreciate all of the helpful responses...
