Physical properties

Hardness: 7 on Mohs scale; Color: Clear to white with orange/brown staining; Luster: Vitreous (glassy); Crystal Structure: Hexagonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65

Formation & geological history

Formed from silica-rich hydrothermal fluids cooling in veins or cavities within various rock types. The orange staining is due to secondary iron oxide minerals (like limonite or goethite) coating the surface or filling cracks.

Uses & applications

Used in electronics, glassware, and as an abrasive. Specimens with aesthetic staining are popular for amateur collectors and metaphysical decoration.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Iron-stained quartz is sometimes referred to as 'Golden Healer' in metaphysical communities.

Field identification & locations

Identify by its ability to scratch glass and lack of cleavage. Commonly found in riverbeds, mountain outcrops, and as vein material. Collectors should look for distinct crystal faces versus massive chunks.
