Physical properties
Hardness: 7 on Mohs scale; Color: Pale yellow to golden honey; Luster: Vitreous/glassy; Crystal structure: Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Formed in igneous rocks (pegmatites) or hydrothermal veins. This specimen appears water-worn, likely tumbled in a river or beach environment. Geological age can range from precambrian to recent depending on the host rock.
Uses & applications
Used widely in jewelry (semi-precious gemstone), crystal healing practices, and as a popular collector's mineral due to its color and availability.
Geological facts
Natural citrine is quite rare; most yellow quartz on the market is actually heat-treated amethyst. It is known as the 'Success Stone' in folklore.
Field identification & locations
Identify in the field by its inability to be scratched by a steel knife and its lack of cleavage planes. Found globally in quartz-rich terrains and alluvial deposits.
