Physical properties

Hardness: 7 on Mohs scale; Color: yellow to brownish-orange; Luster: Vitreous; Crystal Structure: Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & geological history

Formed in igneous and metamorphic rocks, particularly in hydrothermal veins and geodes. Most commercial citrine is produced by heat-treating amethyst or smoky quartz.

Uses & applications

Primary use is in jewelry as a gemstone and for healing crystal/spiritual collections due to its 'success stone' reputation.

Geological facts

Naturally occurring citrine is quite rare; most available on the market is heat-treated amethyst. It is known as the 'merchant's stone' for its association with prosperity.

Field identification & locations

Identify by its translucent yellow hue and 7 hardness (scratches glass). Found in Brazil, Madagascar, and Russia. Collectors should look for internal clarity and saturation of color.
