Thanks for your comment, but why is it so dark? Is there a bluestone that is naturally that dark without it being wet? Thanks in advance

Thank you for visiting our Houzz profile! The coping looks that dark because it is wet. Being a natural product there are variations in color, but to our knowledge there is not a bluestone that would look that dark without being wet. If you are looking for a darker color a suggestion would be to look at Black Absolute Granite. Look at the other photos in our profile there is a pool with a raised spa that has Black Absolute Granite coping with a Bluestone patio.
