Physical properties

Hardness: 7 (Mohs); Color: Clear to white with yellowish-brown staining; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture.

Formation & geological history

Formed in hydrothermal veins and pegmatites through the cooling of silica-rich fluids. The yellow-brown coating is Limonite, which formed later through the weathering of iron-rich minerals.

Uses & applications

Used in electronics as piezoelectric oscillators, in glassmaking, jewelry, and widely collected by metaphysical practitioners and mineral enthusiasts.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Specimens with iron oxide staining are often called 'Golden Healer' in the spiritual community.

Field identification & locations

Identify by its 7 hardness (scratches glass) and conchoidal fracture. Commonly found in mountainous regions worldwide, particularly in Brazil, Arkansas (USA), and the Alps.
