Working Principle

Using 365nm ultraviolet light to irradiate the gemstone can make it emit different degrees of ultraviolet fluorescence. Different gemstones have different Ultraviolet fluorescence characteristics due to different internal compositions and structures. The same gemstone, with different internal trace elements, will also have different ultraviolet fluorescence characteristics.

Attentions

Avoid looking directly at the lamp beads of Ultraviolet fluorescent lamps;

Place the gemstone on a black, non-fluorescent desktop, and the black background is conducive to the observation of gemstone fluorescence;

A jadeite may have partial fluorescence, while the whole jadeite B has fluorescence;

The Ultraviolet fluorescence reaction is only used as an auxiliary identification basis;

The fluorescence of transparent samples is different from that of opaque samples.
