Physical properties
Hardness: 7 on Mohs scale. Color: Pale yellow to brownish-orange. Luster: Vitreous. Crystal Structure: Trigonal. Cleavage: None (conchoidal fracture). Specific Gravity: 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites, often through the natural or heat-treated irradiation of smoky quartz or amethyst.
Uses & applications
Used in jewelry, decorative items, and as a popular crystal in metaphysical practices.
Geological facts
Natural citrine is relatively rare; most commercial citrine on the market is actually heat-treated amethyst.
Field identification & locations
Can be identified by its characteristic yellow color and quartz hardness, commonly found worldwide in association with other quartz varieties.
