Physical properties
Hardness: 7 (Mohs scale); Color: Clear to white with orange/yellow/brown iron staining; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Formed through hydrothermal processes where silica-rich fluids crystallize in veins or cavities. The iron staining occurs when the specimen is exposed to groundwater containing iron oxides, which coat the crystal surfaces.
Uses & applications
Primarily used as a collector specimen or for decorative lapidary work. Pure quartz is used in electronics and glass manufacturing.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. Iron-stained quartz is often jokingly called 'Golden Healer' in metaphysical communities.
Field identification & locations
Identify by its hardness (will scratch glass), hexagonal crystal points, and the fact that the orange color is a surface coating rather than an internal pigment. Commonly found in mountainous regions and riverbeds worldwide.
