Citrine Quartz

Physical Properties

Hardness: 7 on Mohs scale; Color: Pale yellow to golden honey; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & Geological History

Formed in igneous or metamorphic rocks through the crystallization of silica-rich fluids. Natural citrine is rare and often forms when iron impurities in quartz are subjected to natural geothermal heat or radiation.

Uses & Applications

Used extensively in the jewelry industry as a semi-precious gemstone. It is also used in decorative ornaments, crystal healing practices, and as a popular collector's mineral.

Geological Facts

Natural citrine is quite rare; most 'citrine' in the commercial market is actually heat-treated amethyst or smoky quartz. It is known as the 'Success Stone' or 'Merchant's Stone' in folkloric traditions.

Field Identification & Locations

Identify in the field by its hardness (scratches glass), lack of cleavage, and yellow color. Natural specimens typically have a uniform color, whereas heat-treated specimens often appear more reddish-orange or opaque white at the base. Found in Brazil, Madagascar, and Russia.
