No it's not a diamond rock. We finally got back to remodeling our kitchen. We had the hardest time deciding what type of countertops we wanted but finally picked Quartz. They are 100% maintenance free and I love them. Next we are going to put up a tile back splash and paint. Eventually the rest of the appliances will be replaced but as long as they are working they are staying put.
