I purchased the white tile.  From the reviews, I was ready for the tile to be really impressive.  One customer compared it to zellige at an affordable price.  I believe its ceramic tile with a shimmering pearl glaze over it.  Some pieces have more shimmer than others.  The "zellige" look she was talking about is because more shimmer picks up the light and surroundings more than others.  The price was good.  It looks nice but not as high-end as I was hoping for.  The photos are taken at different times of day with lights on and lights off.
