It is my understanding that true Hiddenite does not fade and that is what differentiates it from irradiated spodumene.


I think it's some Afghan hiddenite that comes out of the ground green and turns pink rather quickly when exposed to sunlight; where there is man induced radiation there can always be natural radiation.

Coloured Diopside may fade when exposed to prolonged sunlight.
