The Smoky Quartz
Smoky Quartz is the brown "smoky" variety of Quartz. It ranges in color from light grayish-brown to deep black. Smoky Quartz can be opaque, but is almost always transparent to translucent, even when in its darkest color shade. Smoky Quartz is very common and was never an historically important gemstone. Only in very recent times has it become a popular gemstone.
