Physical properties

Hardness: 7 on Mohs scale; Color: Yellow to honey-brown; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65.

Formation & geological history

Formed in magmatic and hydrothermal environments such as pegmatites and quartz veins. Natural citrine is rare and often forms when amethyst or smoky quartz is heated by geothermal processes.

Uses & applications

Primarily used in jewelry (faceting and cabochons), crystal healing, and as a popular mineral specimen for collectors.

Geological facts

Natural citrine is quite rare; most 'citrine' in the market is actually heat-treated amethyst. It is known as the 'Merchant's Stone' in folklore for its association with wealth and success.

Field identification & locations

Identify by its hexagonal crystal habit, lack of cleavage, and ability to scratch glass. Natural specimens often show color zoning. Frequently found in Brazil, Madagascar, and Russia.
