Physical properties
Hardness: 7 on Mohs scale; Color: Pale yellow to light brown; Luster: Vitreous; Crystal Structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Commonly forms in igneous rocks like granite or in hydrothermal veins. Yellow coloration is often caused by iron impurities or natural/artificial irradiation.
Uses & applications
Used widely in jewelry (birthstone for November), crystal healing, and as a collector's mineral due to its transparency and color.
Geological facts
Natural citrine is quite rare; most commercial citrine is actually heat-treated amethyst or smoky quartz. It is known as the 'Success Stone' in folklore.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. Often found in riverbeds or within quartz veins on hillsides.
