It is a porcelain tile, 12x24 set in a 'soldier course' pattern, and is a grey color. The tile has a reflective quality that is enhanced when either natural or crisp artificial light hits it....it's cool stuff and not terribly expensive. You can call Jeffrey at Cypress Design Center in Eugene, OR at 541-343-0596 and ask him how you can obtain the DC 'Synergy' Home's Main Fireplace Tile. He should be of good help--let him know Dan sent you!
