Noticed the blue too... because blue jadeite (besides the winter-day / smoke - like cold gray called 'blue' sometimes) is only on record from Japan - the blue colour appearing as veins in jadeite rock of the kind geologists talk about & no more (www).
Either this blue is entirely new, perhaps such a rarity that it never made enough news to be remembered by - or the colour is not natural after all.
Thinking out loud
My first thoughts are irradiated. Like how blue topaz gets its colour. Could be legit but am not sure.
