Physical properties

Hardness: 7 (Mohs scale), Color: Pale yellow to golden-brown, Luster: Vitreous (glassy), Crystal Structure: Trigonal/Hexagonal, Cleavage: None (conchoidal fracture), Specific Gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic rocks through hydrothermal activity or crystallization from magma. Natural citrine occurs when quartz is subjected to high heat and radiation within the earth, often over millions of years.

Uses & applications

Extensively used in jewelry (rings, pendants), as healing crystals in metaphysical practices, and as collector specimens.

Geological facts

Natural citrine is quite rare; most 'citrine' in the commercial market is actually heat-treated amethyst or smoky quartz. It is often called the 'Success Stone' or 'Merchant's Stone' in folklore.

Field identification & locations

Identify in the field by its hardness (scratches glass), lack of cleavage, and translucent yellow hue. Look for it in river beds or near pegmatite deposits. It is commonly found in Brazil, Madagascar, and Russia.
