Chocolate Charcoal
Chocolate Charcoal may be used indoors or outdoors for floors, patios, walkways, and walls, landscaping or as a stone veneer. Slabs are available in varied thicknesses depending on type of use. Chocolate Charcoal is a gray/brown quartzite with shiny specks of silver mica on the surface. Quartzite is priced by the ton and is delivered on pallets in both select and patio grade. The thickness of quartzite is very consistent.
