Physical properties
Hardness: 7 (Mohs scale); Color: Colorless to white; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.
Formation & geological history
Formed in all geological environments: igneous (pegmatites), metamorphic (quartzite), and sedimentary. Most clear specimens crystalize from hydrothermal solutions as they cool.
Uses & applications
Used in electronics (oscillators), glass manufacturing, lapidary arts, jewelry, and as professional metaphysical healing crystals.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. It is piezo-electric, meaning it generates an electric charge in response to applied mechanical stress.
Field identification & locations
Identify by its hardness (will scratch glass), lack of cleavage, and transparent appearance. Found globally, with massive deposits in Brazil, Madagascar, and Arkansas, USA.
