How to identify Kunzite
- Check whether the specimen's color and texture match typical Kunzite 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 Kunzite is found
Kunzite is reported from multiple localities or geological settings. Exact locality should be verified from specimen provenance, maps, or field notes.
