=== Smoky quartz === [[Smoky quartz]] is a gray, translucent version of quartz. It ranges in clarity from almost complete transparency to a brownish-gray crystal that is almost opaque. Some can also be black. The translucency results from natural irradiation acting on minute traces of aluminum in the crystal structure.<ref>{{cite journal |last1=Fridrichová |first1=Jana |last2=Bačík |first2=Peter |last3=Illášová |first3=Ľudmila |last4=Kozáková |first4=Petra |last5=Škoda |first5=Radek |last6=Pulišová |first6=Zuzana |last7=Fiala |first7=Anton |title=Raman and optical spectroscopic investigation of gem-quality smoky quartz crystals |journal=Vibrational Spectroscopy |date=July 2016 |volume=85 |pages=71–78 |doi=10.1016/j.vibspec.2016.03.028|bibcode=2016VibSp..85...71F }}</ref>
