The gorgeous gray and veining in the Minera 2x2 Marble Look Matte Mosaic Tile is what gives it warmth as well as visual interest. These veins have a dreamy look that creates a density of detail when cut into 2-by-2-inch squares. Minera is produced with a commitment to environmental responsibility. Its production facility recycles and reuses waste materials and prioritizes renewable energy sources to minimize its carbon footprint. These efforts have resulted in LEED certification for the factory. Additionally, the anti-allergenic Minera is also certified for clean indoor air quality.
