Physical properties
Hardness: 7 (Mohs scale), Color: Pale yellow to golden honey, Luster: Vitreous (glassy), Crystal Structure: Trigonal/Hexagonal, Cleavage: None (conchoidal fracture), Specific Gravity: 2.65
Formation & geological history
Forms in igneous and metamorphic rocks, particularly in pegmatites and hydrothermal veins. Natural citrine is rare and typically forms over millions of years through geological heat and pressure.
Uses & applications
Primarily used in jewelry (faceting and cabochons) and as a decorative collector specimen. It is also highly popular in the metaphysical community.
Geological facts
Most commercial citrine on the market is actually heat-treated amethyst; natural citrine is characterized by a consistent color throughout rather than concentrated at the tips.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. Natural specimens often have a smoky or pale appearance compared to the bright orange of treated stones. Found in Brazil, Madagascar, and Russia.
