Volcano contains quartz, mica, feldspar, garnet and biotite. The shiny flecks of mica give this stone a dramatic and unique look. Because this stone has areas of quartz, which are very hard, and other areas of the slab which are softer due to the high concentration of mica, it is normal for the edge detail to have some wave to it after fabrication.
We source this stone per job from whichever partner yard has the best slab. Installed price = material + $55/sq ft fabrication & installation.
