Physical properties

Hardness: 7 on Mohs scale. Color: Orange to honey-brown. Luster: Vitreous to greasy. Crystal Structure: Hexagonal (trigonal). Cleavage: None (conchoidal fracture). Specific Gravity: 2.65.

Formation & geological history

Formed in igneous and metamorphic rocks, specifically in hydrothermal veins where silica-rich fluids cooled and crystallized. The orange hue is typically caused by hematite or goethite inclusions or trace amounts of iron.

Uses & applications

Used primarily for lapidary work, jewelry (beads and cabochons), decorative home decor, and as metabolic/healing stones in metaphysical circles.

Geological facts

The orange variety of quartz is often naturally occurring but occasionally produced by heat-treating smoky quartz or amethyst. It is chemically identical to glass but has an organized atomic lattice structure.

Field identification & locations

Identify by its ability to scratch glass, its lack of cleavage planes, and its characteristic waxy or glassy luster. Commonly found in Brazil, Madagascar, and the United States.
