Smoky quartz is a popular variety of quartz. It has an unusual color for a gemstone and is easily recognized and is well known by the general public. Only a few other brown or black minerals are ever cut for gemstones such as the smoky topaz, the very rare black beryl or the brown corundum. Smoky quartz is also popular as an ornamental stone and is carved into spheres, pyramids, obelisks, eggs, figurines and ornate statues.
