Described as butterfly blue, this black granite features specs of blue mixed with greens, grays, and browns to form a dark and distinctive basin. Although this vessel measures square, its sides gracefully bow slightly outward. Its bold 1" thickness and hand-polishing reaffirms that it is a solid choice. With an overall measurement of 15 3/4" x 15 3/4" x 5 3/4", it will require a minimum-width cabinet of 18". This listing does not include any accessories.
