Although I can't say for sure the backsplash looks very similar to Heath ceramics work

Definitely Heath Ceramics....so pretty.

How durable is the backsplash? Is it good for behind a stove?

Does anyone know the name of the backsplash from Heath?

The Heath tile is generally referred to as "dimensional" tile and if you go to their website and click on dimensional tile, you will see the various styles and all color options. It's costly!
