Crafted from fine natural sandstone, our Mountain Bluestone Wall Caps feature a deep charcoal gray with just a hint of a blue undertone. Use these wall caps to finish off fireplace hearths, fountains and other features, planter boxes, retaining walls, and other architectural elements as desired. They coordinate beautifully with a wide range of products in our inventory including pavers, stacked stone panels, natural stone countertops, and wall and floor tiles.
