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
Forms in igneous rocks like granites and pegmatites through hydrothermal processes. Most commercial citrine is actually heat-treated amethyst or smoky quartz.
Uses & applications
Widely used in jewelry (faceting and cabochons), meditation/metaphysical practices, and as collector specimens.
Geological facts
Citrine is known as the 'Success Stone' or 'Merchant's Stone.' It is one of only two minerals on Earth that does not hold or accumulate negative energy, but dissipates it. It is the birthstone for November.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. In the field, look for hexagonal crystal shapes. Naturally occurring citrine is rare and usually found in Brazil, Madagascar, and Russia.
