Physical properties
Hardness: 7 Mohs; Color: Pale yellow to golden brown; Luster: Vitreous; Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.65
Formation & geological history
Formed in igneous and metamorphic rocks, particularly geodes and veins. Most commercial citrine is heat-treated amethyst or smoky quartz.
Uses & applications
Primarily used as a gemstone in jewelry (earrings, rings, necklaces) and by collectors and spiritual practitioners.
Geological facts
Natural citrine is rare; it is known as the 'Success Stone' or 'Merchant's Stone' in folklore. Its yellow color comes from submicroscopic iron impurities.
Field identification & locations
Identify by its glass-like luster and yellow hue. Natural specimens show pleochroism, while heat-treated versions often have a white base. Found in Brazil, Madagascar, and Russia.
