Thank you for your question. The backsplash is made up of honed and leathered Carrara marble pieces.
The border is a chair rail and inside that is a metal strip that is made by
Estate Metals by Sonoma Tile Makers. The one the client chose is the 1/2" by
8" Van Ness. You can find it on this link at the very bottom:

After the metal border is a 1x1 mosaic tile followed by another metal
border. Inside the backsplash is a 1x2 herringbone patterned marble tile.

Wehope this information was helpful. Our client made all
their selections at a local tile showroom called Hamilton Parker. We checked over
the order acknowledgement and it read that the tiles for the backsplash came
from the Rue Pierre collection. This is a collection from Walker Zanger. Here
is a link to that collection:

I hope this
information was helpful. Please let me know if you have any other questions, and best of luck with your project. Thank you for visiting our Houzz page.
