Bluestone is a natural stone. It is sedimentary rocks- limestone that appear blue-gray in color. The most common types of bluestone consist of sediments that underwent millions of years of compression to become stone.
Bluestone is a very high dense material. Its natural ability to withhold harsh and unfriendly weather conditions is amazing. It is also resistant to freeze-thaw cycles.
