These are really special tiles.  They aren't shiny cheap looking pearlescent as the photos appear but they seem handpainted with a sparkly paint that has almost a matte finish.  They do have a very slight peach undertone so be cautious of that.  They looked very high end in our kitchen remodel.  I'm not sure I would use them again in a white kitchen because you can't see the pearl finish enough to justify the price over a regular subway tile and they fought a touch with the Pental Avenza counters.  They're a showpiece item to be sure so find a place with great light and no other bright whites and you'll be in love.
