This rich black igneous rock is characterized by a medium grain size which displays a subtle patterning and depth of color when honed, polished or water jetted. Basalt is formed from volcanic action and lava flows, which contribute to its uniform and consistent appearance. Because basalt is unique in how it is harvested, it limits the sizes available for fabrication.
