Physical properties

Hardness: 7 on the Mohs scale. Color: Yellow to brownish-orange. Luster: Vitreous (glassy). Crystal Structure: Trigonal. Cleavage: None, exhibits conchoidal fracture. Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins, pegmatites, and metamorphic rocks. Natural citrine is rare, and much commercial citrine is created by heat-treating purple amethyst or smoky quartz.

Uses & applications

Used widely in jewelry, as decorative crystal towers or points, in crystal healing practices, and by collectors.

Geological facts

Natural citrine gets its yellow-to-orange color from sub-microscopic colloidal dispersion of iron hydroxide. The name comes from the French word 'citron', meaning lemon.

Field identification & locations

Identified by its yellow-orange color and a hardness of 7 which easily scratches glass. It is commonly found globally, with major deposits in Brazil, Madagascar, and the USA.
