Physical properties

Hardness: 7 on Mohs scale; Color: Pale yellow to golden honey; Luster: Vitreous (glassy); Crystal structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65

Formation & geological history

Formed in igneous (pegmatites) or metamorphic rocks. Natural citrine is rare and colored by iron. Most commercial specimens are amethyst or smoky quartz that has been heat-treated to achieve the yellow/orange color.

Uses & applications

Commonly used in jewelry (facets, beads, and cabochons), crystal healing collections, and as decorative stone specimens.

Geological facts

Natural citrine is often called the 'Success Stone' or 'Merchant's Stone.' It is the birthstone for November. Heat-treated specimens often show a white base and a more opaque, reddish-orange tip compared to uniform natural citrine.

Field identification & locations

Identify by its hardness (will scratch glass) and lack of cleavage. Look for the transparent yellow hue. Commonly found in Brazil, Madagascar, Spain, and Russia. Collectors should look for 'natural' (non-heated) labels for higher value.
