Physical properties
Hardness of 7 on Mohs scale, yellow to orange color, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms hydrothermally in igneous or metamorphic rocks, often naturally via the heat-driven irradiation of amethyst.
Uses & applications
Widely used in jewelry, decorative carvings, and as a popular collector specimen for crystal enthusiasts.
Geological facts
Natural citrine is relatively rare, with the vast majority of commercial citrine produced by heat-treating purple amethyst.
Field identification & locations
Identified by its distinct yellow-to-orange color and lack of cleavage; commonly mined in Brazil, Madagascar, and Russia.
