Smoky quartz is an earth-toned transparent quartz that comes in a variety of shades, including cognac. Smoky quartz gets its rich warm colors from color centers when aluminum replaces silica in the crystal lattice of the quartz after exposure to gamma rays. A popular ornamental stone, it is often carved into figurines and ornate statues, but makes quite a statement when faceted into stunning gemstones.
