Seagrass is quarried from a bedrock quarry in Eflani, Karabuk, Turkey. It is a sedimentary stone formed on shallow sea beds from monsoonal rains washing minerals, plants and animals into the sea. Structurally, Seagrass is a very hard limestone. Some common characteristics that are visible in this limestone are quartz veins, grey portions and many fossilized shells in each piece. There will be some variance between pieces, so it is important to view a range of the product. Arizona Tile stocks Seagrass in a honed finish. As a natural stone product, it is recommended that this be sealed to extend its longevity.
