I think it's a picture either from Canadian House and Home or Style at Home.

That is gorgeous!
I wonder if you could find it through this co.

It is beautiful, I love that look. At first I thought it might be one a Sarah Richardson kitchen, but can't find it in her portfolio.

The look is called Culture Brick or Cultural Brick and here's one link I found.

I've also seen it called linear brick or just linear mosaic at BuyTile. I can't find a good color match, but they have that shape in Dolomite...

Here you go.

I have this in my picture file.
Lots of great ideas in this kitchen in addition to a very nice backsplash. Tile source on page 4.

Thank you everyone! Lisa, I plan to call the source for that stone first thing in the morning. I'll let you know how it works out. I've been in a desperate search for a backsplash....I think you have helped me find it.

Love that backsplash!! Thank you for posting and thank you Lisa for finding it!
