Physical properties

Hardness: 7 on Mohs scale; Color: Colorless to transparent; Luster: Vitreous (glass-like); Crystal structure: Hexagonal/Trigonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65.

Formation & geological history

Formed through the crystallization of silica-rich magma or from hydrothermal veins. It occurs in all types of geological environments (igneous, metamorphic, and sedimentary) and can be over 100 million years old depending on the deposit.

Uses & applications

Used widely in electronics (oscillators), optical instruments, glassmaking, and extensively in jewelry and as healing crystals in the metaphysical community.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. It is piezo-electric, meaning it generates an electric charge when mechanical pressure is applied.

Field identification & locations

Identify by its ability to scratch glass, its hexagonal point structure, and lack of cleavage. Commonly found in mountainous regions globally like Arkansas (USA), Brazil, and the Alps.
