This is our new design marble and glass tile. It is interlocking patterns design with teal blue crystal glass and grey nature marble. The color of the marble chips is random, some chips looks grey and some chips are darker, because they are all made from nature stone, we keep their nature color, did not add any artificial dyer, and we only polish the surface of the stone to make it glossy. The color on all blue crystal tile is kiln fired onto back of tile, not painted on, which means it will never scratch, chip, fade or peel. This tile is very beautiful for bathroom floors, bathroom walls, showers, kitchen backsplash and kind of interior application.
