Absolutely gorgeous.  Worth every penny for the way it looks as a backsplash at the beach.  We wanted to bring in natural elements that were coastal without being kitschy and these were the perfect touch paired with white cabinets.  The iridescent shine of the mother of pearl tiles pairs beautifully with our countertops. I was concerned about how much brown would be in these tiles, but was thrilled that they were truly white and trending towards gray.  These are still a natural material so they're not dead white - but they're definitely not yellow or brown.  We had several options of granite/quartz countertops that this worked with - I do recommend having a sample on hand when you're choosing countertops just to be sure.
