The gorgeous gray and gold veining in the Minera Sahara Blanco White 2x2 Marble Look Matte Mosaic Tile is what gives it warmth and visual interest. These veins have a thin angular pattern cutting in all directions 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 in Spain 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.
