For a long time, as long as there is fluorescence reaction, many people will think that real jadeite has no fluorescence under ultraviolet light, while epoxy resin as filler of B jadeite will have fluorescence under fluorescent light.
As we all know, you should know that ultraviolet light is actually a sharp weapon to test the authenticity of jadeite, but it can't detect counterfeit jadeite made of other materials. The reason why A "Emerald" will have a fluorescent reaction under the purple light may be that she just mentioned that B Emerald filler epoxy resin will fluoresce under the fluorescent light. This is why the jadeite dyed by acid washing can be identified by ultraviolet lamp.
Of course, in addition, there are fluorescence reactions, and it is also possible:
1, waxing, that is, coating a layer of colored or colorless wax on the real jade ornaments; This situation needs special attention, because a certificate of genuine jade may be issued. However, after waxing, unscrupulous merchants will "facelift" jadeite with poor quality into jadeite with good water quality and good color, and sell it at a high price. Fortunately, as long as you are under ultraviolet light, these ghosts will show their true colors;
2. There is another situation, which is very rare. It's really real jade. It hasn't been treated, but it's doped with too many stone impurities and fluoresces under the ultraviolet lamp. However, the appearance of this "real jade" is generally the same as that of stone, and the appraisal agency does not call it jade, so it has no commercial value.
In addition, if there is no fluorescence reaction under ultraviolet light, is it real jade? Not necessarily, it may be real jade, or it may be what we call "D-quality jade", that is, jadeite made of dyed green agate, dyed quartzite, dyed glass, dyed jade, dyed prehnite, etc., which is passed off after being discolored.
To sum up, that is: jadeite with fluorescence reaction must be treated; Without fluorescence reaction, it can't be proved to be real jade.
