These two possibilities have little influence on whether the jade itself is A goods. If you mind, you can remove it with warm water, neutral detergent, brush, and jewelry cleaning machine. After cleaning, the previous blue fluorescence will disappear after being irradiated with fluorescent light.

Jade bracelets, under fluorescent lamps, have a little fluorescence, which is not the standard for judging authenticity. I suggest you take some photos and upload them in natural light so that I can give you detailed comments and evaluations.

We think that fluorescence is very good, and the light emitted is called fluorescence, but the fluorescence you understand should be another meaning, that is, the fluorescence generated by using polishing powder during jade processing. This is not allowed. Only those with poor quality will use polishing powder.

No, there will be a fluorescent reaction under special blue light. It must be B. A goods won't have any fluorescence.
