Physical properties

Formation & geological history

Quartz forms in silica-rich veins and cavities as hot fluids cool; its age depends on the host deposit and cannot be determined from appearance. Citrine’s color commonly results from iron-related defects, sometimes enhanced by heating amethyst.

Uses & applications

Used in inexpensive jewelry and as a collectible gemstone; similar-looking yellow stones include glass and other minerals.

Geological facts

Natural citrine is relatively uncommon; much commercial citrine is heat-treated amethyst. A photo alone cannot confirm the material or treatment.

Field identification & locations

Check hardness and refractive properties with gemological tools; quartz should scratch glass, though this test can damage a cabochon. Citrine is found in Brazil, Madagascar, Zambia, and elsewhere.
