Hi Carrie, This looks like cararra marble mini bricks. Here is one source: http://www.artistictile.net/store/product3235.html
Cararra can vary in color and tone, so be sure to request a current sample before purchasing.

Thank you!

No problem. Good luck!

Are there different colors? The link shows a color with silver undertones, whereas the picture shows tile that has gold undertones (although I may be totally wrong).

I found an identical tile at the tile shop called Taishan Ivory Polished Cardine 12 x 12 in. The link is: http://www.tileshop.com/naturalstone/travertine/Taishan-Ivory-Mosaics/2019.aspx

Can you tell me what color grout was used?

this is not carrara tile

Agreed Liaper.

Is it Calacatta? It is easy to get cararra and calacatta marbles confused.

Hi ds studio design, The retailer does not specify what marble it is, they refer to it just as polished marble mini brick, called 'Milky Way'. You are absolutely correct, each batch can be different from the sample featured, so it is smart to get a sample of the current 'lot'.

hello Carrier, we have production lines especially produce back splashes, if you like you can contact with our colleague Ms Lily who is in charge of this, her email is lily_cfmosaic@163.com, our website is http://www.connflymosaic.com/en/product.asp, we export to USA a lot.
