Citrine
Silicon dioxide (SiO2)
Rock Type: mineral

Physical Properties
Hardness: 7 (Mohs scale); Color: Pale yellow to golden honey or brownish orange; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (Trigonal); Cleavage: None (Conchoidal fracture); Specific Gravity: 2.65
Formation & Geological History
Citrine is a variety of quartz that develops when amethyst or smoky quartz is naturally heated deep within the earth. It is often found in pegmatites and hydrothermal veins. Natural citrine is rare; many commercial stones are heat-treated amethyst.
Uses & Applications
Primarily used in jewelry (rings, pendants, earrings), as a birthstone for November, and in crystal healing collections. It is valued for its durability and clarity.
Geological Facts
Known as the 'Merchant's Stone' or 'Success Stone' in folklore, it was believed to bring prosperity. It is one of the few gemstones that is thought to not hold or accumulate negative energy, but rather transmutes it.
Field Identification & Locations
Identify in the field by its hardness (scratches glass) and lack of cleavage. Natural citrine usually has a consistent yellow/gold tone, whereas heat-treated material often has a reddish tint and a matte white base at the root. Found in Brazil, Madagascar, and Russia.
