Physical properties
Hardness: 7 on Mohs scale; Color: Pale yellow to honey gold; Luster: Vitreous (glassy); Crystal Structure: Hexagonal; Specific Gravity: 2.65.
Formation & geological history
Formed in igneous or metamorphic rocks through hydrothermal processes. The yellow color is typically caused by ferric iron impurities or radiation. Many commercial specimens are heat-treated amethyst.
Uses & applications
Used primarily in jewelry as a semi-precious gemstone, for chakra and crystal healing, and as decorative tumbling material.
Geological facts
Natural citrine is quite rare in nature. Most yellow quartz found in shops today started as purple Amethyst that was artificially heated to change its color.
Field identification & locations
Identify in the field by its distinct hardness (scratches glass) and lack of cleavage. Found in river beds or as alluvial deposits in Brazil, Madagascar, and Russia.
