Geology & background
Natural citrine forms when amethyst is heated by nearby magmatic activity. Most commercial citrine is heat-treated amethyst.
Popular in ancient Greece for decorative gems, citrine saw renewed popularity in the Art Deco period.
How to identify Citrine
- Check whether the specimen's color and texture match typical Citrine examples.
- Photograph a fresh surface in natural light and avoid shadows, glare, or wet surfaces.
- Use hardness, streak, luster, grain size, and locality together; no single trait is enough for every specimen.
Where Citrine is found
Citrine is reported from multiple localities or geological settings. Exact locality should be verified from specimen provenance, maps, or field notes.
