Stacked ledge stone is most often used for fireplaces but is also great for bars, backsplashes and accent walls. It's easily installed requiring only a few tools (wet saw, trowel, level).
Volcanic (not actual lava) is a natural marble and has a soft vein throughout. It is primarily medium-black stone and really is amazing installed. Pre-made corners are available and interlock with the interlocking 6x24 panels.
