The tile are custom made at our facility in California. The field tile are the "shell series" and cost $42.00 per square foot. The base pieces cost $16 per piece and they give you that flat edge, a similar piece can be manufactured for the top edge at the same price, but if you a fitting under cabinets you don't need the top edging. The Square field tile on the counter top measure 8" x 8" and run about $38 per square foot. We blended the glaze colors Chicago Green and Celadon. Please give us 4-6 weeks to manufacture. We'd love to help!!
