Physical properties

Hardness: 7 (Mohs scale), Color: Yellow to brownish-orange, Luster: Vitreous, Crystal structure: Hexagonal (trigonal), Cleavage: None (conchoidal fracture), Specific gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic environments, frequently within pegmatites or hydrothermal veins. Natural citrine is rare and often forms when amethyst is subjected to natural geothermal heat over long periods.

Uses & applications

Primarily used in jewelry (rings, necklaces), as a collector's gemstone, and in spiritual/metaphysical practices as a 'success stone'.

Geological facts

Most citrine on the commercial market is actually heat-treated amethyst or smoky quartz. Natural citrine usually appears in a much paler, consistent yellow color compared to the darker orange of treated specimens.

Field identification & locations

Identify in the field by its hardness (scratches glass) and lack of cleavage. It is found in Brazil, Madagascar, and Russia. Look for translucent yellow transparency with no visible banding.
