Mineral (Variant Of Quartz)

Granite

Granite — a coarse-grained felsic intrusive igneous rock, typically composed of quartz, feldspar, and mica

Druzy quartz (quartz-lined rock fragment)

Quartz, SiO₂; likely a druzy coating on a host rock

Milky Quartz with Iron Staining

Quartz (Silicon Dioxide, SiO2)

Likely smoky quartz

Quartz, SiO₂ (smoky variety)

Quartz Vein in Host Rock

Silicon Dioxide (SiO2) within Metasedimentary or Igneous Matrix

Quartz (Druzy) in host rock

SiO₂ (Silicon Dioxide) as Quartz, with unspecified host rock components (likely silicates and iron oxides)

Gold-bearing Quartz

Native Gold (Au) in Quartz (SiO2) matrix

Rutilated Quartz

Quartz with Rutile inclusions (SiO2 with TiO2 inclusions)

Quartz-bearing pegmatitic rock with feldspar

Granitic pegmatite; chiefly quartz (SiO₂), feldspar, and mica

Quartz (Milky or Cloudy)

Silicon Dioxide (SiO2)

Milky Quartz
