#Quartz is a #crystal form of #SiliconDioxide (#SiO2) in a trigonal crystal system.
Other #mineral forms of silicon dioxide exist, but quartz is probably one of the most common.
Other things can be included into the crystal, or the crystal structure can be deformed, both of which are forms of #flaws in the crystal.
