What Is
Bluestone?
Bluestone is a dense, fine-grained sandstone found primarily in the northeastern United States. It gets its characteristic blue-grey color from the minerals — primarily quartz and feldspar — that make up its composition. It splits naturally along flat planes, which is why it has traditionally been used as a paving and stepping stone material. Its density makes it more durable than many sandstones.
Bluestone has a distinctive blue-grey to greenish-grey color with a naturally cleft, textured surface. When dry it appears muted; when wet or sealed it deepens to a rich charcoal blue. It can be used with its natural cleft surface for maximum texture and traction, or thermal-finished for a more uniform appearance. Its color and texture make it a classic choice for traditional and contemporary exterior design.
