Physical properties

Hardness: 7 Mohs; Color: Pale yellow to golden honey; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (Conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed in igneous or metamorphic environments when amethyst or smoky quartz is subjected to natural geothermal heat or as a primary crystal in pegmatites. Natural citrine is rare compared to heat-treated varieties.

Uses & applications

Highly valued for semi-precious jewelry, ornamental stone carving, and as a popular specimen for mineral collectors and crystal healing enthusiasts.

Geological facts

Natural citrine is quite rare; most 'citrine' on the market is actually heat-treated amethyst. Natural citrine usually has a consistent pale yellow color compared to the burnt orange-red tips of treated specimens.

Field identification & locations

Identified by its conchoidal (glass-like) fracture, 7 hardness (scratches glass but not topaz), and lack of cleavage. Often found in Brazil, Madagascar, and the Ural Mountains.
