Physical properties

Hardness: 7 on Mohs scale; Color: Clear to white with orange-red iron staining; Luster: Vitreous (glassy); Crystal structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture).

Formation & geological history

Formed in hydrothermal veins or pegmatites as cooling silicon-rich fluids crystallize. The orange hue is caused by iron oxides (limonite or hematite) leaching into cracks or coating the surface over geological time.

Uses & applications

Primarily used for decorative purposes, crystal collecting, or as a source of quartz for industrial applications like electronics and glass-making.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Iron-stained quartz is sometimes markets as 'Hematoid Quartz' or 'Fire Quartz' in the metaphysical community.

Field identification & locations

Identify in the field by its hardness (will scratch glass), lack of cleavage, and glassy appearance. Commonly found in riverbeds, mountain terrains, and near mining sites globally.
