Physical properties
Hardness: 7 on Mohs scale; Color: Orange to reddish-orange; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture.
Formation & geological history
Formed when iron-rich water evaporates on the surface of quartz crystals, leaving a microscopically thin coating or inclusions of hematite (iron oxide).
Uses & applications
Primarily used as a collector specimen, in metaphysical practices, and occasionally in artisanal jewelry.
Geological facts
The orange color is not inside the crystal structure itself, but is a coating of rust-like iron minerals on the surface or just beneath the surface interface.
Field identification & locations
Identify by its distinct orange coating over transparent to translucent quartz points. Commonly found in Minas Gerais, Brazil and Madagascar.
