I am using this tile and am going with a light ceramic/porcelain type that has a stone type look to it. The tile has a straight edge. It is called Opus but I am not sure if it is widely available.

I just love that tile. Could you please tell me how expensive it is. Thank you so much.

Thanks for the replies. My search continues -- the glass tile looked too blue for the kitchen (but is at the top of the list if we ever move on to bathrooms). At the tile stores near me, the Vihara Karuna brick style (like pictured) was arounc $22-23/sf (retail price).
