Physical properties

Formation & geological history

Formed from cooling silica-rich magma or from hydrothermal veins. The iron staining occurs when the specimen is exposed to groundwater containing dissolved iron minerals which precipitate onto the surface or into micro-fractures.

Uses & applications

Used extensively in the glass industry, electronics (piezoelectric properties), and as decorative specimens or metaphysical stones. Natural crystals are popular for amateur collectors.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Iron-stained quartz is often mistakenly called 'Tangerine Quartz' or 'Golden Healer' in metaphysical communities.

Field identification & locations

Identify by its hardness (scratches glass), conchoidal fracture (curved glass-like breaks), and lack of cleavage. Common worldwide in nearly all geological environments. This specific piece shows a typical rough, naturally weathered appearance.
