Does every dyed jadeite fluoresce under UV? |

Ive seen videos of jadeite jade been tested from second-hand markets that don't show uv fluorescence but still come out as injected jade so its hard to tell even if you have a Chinese COA with it with grade A. Its best to send it to GIA or a trusted COA store. The answer to your question is Yes and No, Best to test it with a UV and see but most type C or grade C will show UV fluorescence. |

The only sure way to tell is with either Raman or FTIR spectroscopy. |
