Physical properties

Hardness: 7 (Mohs scale); Color: pale yellow to golden honey; Luster: vitreous (glassy); Crystal structure: Hexagonal/Trigonal; Cleavage: none; Specific gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic rocks, particularly in pegmatites and hydrothermal veins. Natural citrine is rare; many commercial specimens are heat-treated amethyst or smoky quartz.

Uses & applications

Primarily used in jewelry (faceting, cabochons) and as a decorative collector's stone. It is a popular 'healing crystal' in metaphysical circles.

Geological facts

Natural citrine is often called the 'Success Stone' or 'Merchant's Stone.' Heat-treated citrine usually has a reddish tint and a white opaque base, whereas natural citrine is typically a uniform pale yellow.

Field identification & locations

Identify by its hardness (scratches glass) and lack of cleavage. Found commonly in Brazil, Madagascar, and Russia. This specimen is polished into a palm stone or worry stone shape.
