Physical properties
Hardness: 7 on Mohs scale; Color: Colorless/Transparent; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments. Typically crystallizes from magma or hydrothermal cooling. Can be found in veins or as larger geode formations.
Uses & applications
Used widely in electronics (oscillators), glass manufacturing, jewelry, and as decorative metaphysical crystals.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. It is piezoelectric, meaning it generates an electric charge when mechanical pressure is applied.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. Look for six-sided prismatic crystals terminating in pyramids. Commonly found in pegmatites and mountain ranges.
