So glad you like it. It adds a pop of something special without being at all overwhelming.
The tiles were sourced from Cerdomus Tile Studio in Richmond Victoria. They call them 100 x 300 Black Shadow Matt and have a code of MM1330 for the tiles. If you were to contact Cerdomus on 03 9428 4326 they may be able to assist you.
And the grout is a Mapei turquoise no. 171.
Thanks for the question.
