Was looking to achieve an aged look in a new tile installation for a fireplace hearth in a vintage home, and this hit the mark.  Although a 13"x13" tile, the grooved 'dividing 'lines' give the appearance of grout lines between smaller tiles, making this a nice choice for those who may be looking for the simpler installation (especially if covering larger square footage) that a larger tile provides--but with the look of a mosaic!
