Physical properties

Hardness: 7 on Mohs scale; Color: Clear to milky white; Luster: Vitreous to greasy; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65.

Formation & geological history

Formed via hydrothermal activity where silica-rich fluids cool and precipitate in cavities of rocks. It can be found in igneous such as pegmatites, metamorphic geofes, or sedimentary environments.

Uses & applications

Used in semi-precious jewelry, high-end watches, electronics (due to piezoelectric properties), and as decorative collector specimens.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Druzy refers to a coating of fine crystals on a rock surface that looks like sugar.

Field identification & locations

Identify by its hardness (scratches glass), lack of cleavage, and characteristic hexagonal crystal terminations. Commonly found in geodes and mountainous regions worldwide.
