I am doing a small kitchen up date. I found a granite counter that has a lot movement that I love (sienna bordeaux), I want the back splash to be tumble Botticino tiles. I have one place that I would like to put two 4 x 4 tiles of the tumble stone but would like a small etching of herbs or a flower on them.....no color. So it blends into the tiles, yet looks different. Is there anyplace that I can purchase something like this. All the decorative tiles I see are metallic , very fancy or regular ceramic tiles.

Thank you for any advice
