Physical properties

Hardness: 7 on Mohs scale; Color: Orange to reddish-orange; Luster: Vitreous; Crystal Structure: Trigonal; Cleavage: None; Specific Gravity: 2.65

Formation & geological history

Formed through the oxidation of hematite or goethite on the surface of quartz crystals, often in hydrothermal veins or sedimentary deposits.

Uses & applications

Primarily used for gemstone collecting, jewelry making, and metaphysical or decorative purposes.

Geological facts

The orange color is not inside the crystal but is a crust of iron oxide on the surface. If soaked in certain acids, the orange coating can be removed to reveal clear quartz.

Field identification & locations

Identify by its distinct orange coating over a hexagonal crystal structure. Commonly found in Brazil and Madagascar. Collectors look for undamaged terminations.
