The Ako Multi Color Mix 4x9 Rectangle Marble Micro Mosaic has a sophisticated, retro vibe. The polished, multicolored tile is composed of many marbles, including Rossa Red, Portugal Gray, Blue Macauba, Verde, Bardiglio, and Indus Stone. Every stone is carefully selected for color and quality, and artfully arranged into versatile, 4-by-9-inch rectangles. Ako makes a great accent tile, especially in smaller spaces.
