Physical properties

Hardness: 7 on Mohs scale; Color: Pale yellow to deep honey amber; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

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

Uses & applications

Used extensively in jewelry (beads, cabochons, faceted stones) and as a birthstone (November). It is also a popular specimen for metaphysical collectors and mineral enthusiasts.

Geological facts

Natural citrine is often called the 'Success Stone' or 'Merchant's Stone' in folklore. Most citrine sold today is actually amethyst heat-treated to roughly 470-560 degrees Celsius to achieve the yellow hue.

Field identification & locations

Identify in the field by its hardness (scratches glass), lack of cleavage, and transparent to translucent clarity. Commonly found in Brazil, Madagascar, and Russia. Natural citrine usually has a consistent color, whereas heat-treated pieces often have white powdery bases.
