Quartz is the most common mineral in the face of the earth. Chemically, quartz is a compound called silicon dioxide, SiO2. As a quartz crystal is used as a semiprecious gem. Quartz is a relatively hard stone, 7 on the Mohs hardness scale.
Quartz is one of the most abundant mineral crystals and can take many ways. Quartz is a piezoelectric material that moves when placed in an electric field. It has been applied in various devices such as an oscillator. Quartz is used extensively industry and used in radio and, especially, had an impact in the watch industry.

Brazil currently produces the bulk of smoky quartz pieces as lapidary improved. Smokey: Crystals can weigh up to 650 pounds. have been found in Brazil.
