The answer depends on the type of jade. Jadeite, the more valuable type, does not fluoresce under UV light. However, nephrite, the less expensive variety, may exhibit a faint fluorescence in some cases.
Factors Affecting Jade's Fluorescence:
- Type of Jade: Jadeite generally does not fluoresce, while nephrite can show faint fluorescence.
- Trace Minerals: The presence of trace minerals, like manganese or iron, can influence fluorescence in nephrite.
- UV Wavelength: Different UV wavelengths can evoke different fluorescence responses.
Practical Implications:
- Gem Identification: Fluorescence can be a helpful tool for distinguishing jadeite from nephrite.
- Collecting: Some nephrite jade specimens are sought after for their fluorescence under UV light.
In conclusion, while jadeite does not glow under UV light, some nephrite jade varieties may exhibit faint fluorescence due to the presence of trace minerals.
