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 :cry: 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.
