Physical properties

Hardness: 7 on Mohs scale; Color: Yellow to brownish-orange; Luster: Vitreous; Crystal system: Trigonal/Hexagonal; Cleavage: None; Specific gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic environments, specifically in pegmatites or hydrothermal veins. Natural citrine is rare and often forms when amethyst or smoky quartz is naturally heated by geothermal processes.

Uses & applications

Primarily used in jewelry (faceting and cabochons), as decorative specimens for collectors, and in metaphysical practices as a 'success stone'.

Geological facts

Most commercial citrine is actually heat-treated amethyst. Natural citrine is pale yellow and dichroic, meaning it shows different colors from different angles, unlike the burnt-orange heat-treated variety.

Field identification & locations

Identify by its hardness (scratches glass), lack of cleavage, and yellow-gold clarity. Commonly found in Brazil, Madagascar, and Russia. Collectors look for clarity and natural honey-yellow hues.
