Physical properties
Hardness: 7 on Mohs scale; Color: Pale orange to peachy-pink; Luster: Vitreous to waxy; Crystal structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific gravity: 2.65.
Formation & geological history
Forms in igneous rocks like granite through cooling magma or in hydrothermal veins. The orange tint is typically caused by iron oxide inclusions (hematite or limonite) during or after the crystal formation.
Uses & applications
Mainly used for crystal collecting, metaphysical purposes, landscaping, and occasionally as a semi-precious gemstone in jewelry or carvings.
Geological facts
Quartz is one of the most abundant minerals in the Earth's crust. Orange quartz is often called 'Tangerine Quartz' in the metaphysical community, though that term usually refers to specimens with a specific surface coating of iron.
Field identification & locations
Identify by its ability to scratch glass and its lack of cleavage. It is commonly found in Brazil, Madagascar, and the USA. Collectors look for clarity and intensity of the orange hue.
