Physical properties

Hardness: 7.0 (Mohs); Color: Pale yellow to golden yellow; Luster: Vitreous; Crystal Structure: Trigonal; Fracture: Conchoidal; Internal: Heavily fractured/crackled effect.

Formation & geological history

Formed in igneous and metamorphic rocks as quartz crystals during the cooling of silica-rich magma or hydrothermal activity. This specific specimen has been heat-treated and likely thermal-shocked.

Uses & applications

Commonly used in jewelry, as decorative tumbles, and in metaphysical practices as a 'stone of abundance'.

Geological facts

Natural citrine is rare; most citrine on the market is heat-treated amethyst or smoky quartz. The 'crackled' look is achieved by heating the stone and then quickly cooling it in water to create internal fractures.

Field identification & locations

Identify by its yellow color and quartz-like transparency. In the field, look for hexagonal prisms. Common locations include Brazil, Madagascar, and Russia.
