The gray stone backsplash tile both have glittering crystal glass mosaic chips and stone mosaics. the stone chips color will not be always same which means the stone chips may have color variation, some even have wave marks on the finish. However, it is just showing the nature beauty. As for the glass chips, high-temperature make they stable and durable, the colors will never fade away. We added rose gold stainless steel chips in this glass tile which will reflect and make room seem luxurier. Each sheet of the blue glass tile backsplash is approximately 1 square feet (12 x 12 inches) and mesh mounted for easy installation. This glass stone blue mosaic is very beautiful for kitchen backsplash, accent walls, bath and shower walls.
