The old question… as suggested by ‘Wives tales(just an expression,
ladies)’, Rumors, and Gossiper …It’s the same question as,
Does Bubble Gun Loss its flavor on the bedpost over
night???.. If you ‘ain’t, done it’ you don’t really
know the answer …
… An so, … 'If you haven’t owed one for a period of time, you don’t
know the answer!!!
Does Kunzite loose its color when worn in sunlight over a
2/3 year period … and that’s why its called the night
stone???
Does Morganite......
And last ... is this true for ALL PINK stones
… Gemologist need not apply … unless you have OWNED THESE
STONES(maybe as crystals and left outside, the for several
years, EXPOSED them to the sun light

Well, I don’t know about Morganite, but yes Kunzite looses it colour very
quickly - a noticeable change within even a few days, when left in sunlight.
Not recommended!! If I remember correctly the colour change is permanent,
although don’t quote me on it. There are some stones that fade in sunlight, but
then come back if you put them in a dark corner of your dresser.

All natural Kunzite can fade with long exposures to sunlight.Look out for a
minty green color spodumene,not Hiddenite,more minty.this is likely to be
Brazilian light Pink Kunzite or White Spodumene irradiated.This material
will fade in just a couple of hours under even a 100 watt light bulb.
Pink Morganite is not light sensitive,and is stable to heating up past 500F
Natural Orange Morganite upon exposure to sunlight for anywhere from a few
days to 2 weeks will change to the same intensity of Pink color.This can be
induced more rapidly by heat treatment.

So you are saying that Kunzite fades in sunlight… HOWEVER, Morganite, with
heat, becomes a darker PINK!!!

Yes,Natural Orange Morganite turns Pink on heating or even with a week or
two in direct sunlight.And I saw your earlier post about what other stone
do this.there are many.Most notable is Amethyst to Citrine.In Bahia,Brazil
they pace Amethyst in direct sunlight to make Citrine.They will bury it
under sand to increase the heat factor,to speed it up.The color progression
in Amethyst is Purple to White and then into Citrine.

Yes kunzite can loose colour worn daily or even regularly and
immersed in detergents (washing dishes etc.).or everyday activities
of practical life… Kunzite bought say, ten years ago or more was
even more subject to fading. before gemmy kunzite flooded the market
(from primarily Chinese cutting centers) when cutters were cabbing
thick “blades” it was not being stabilised or treated as it is
commonly- today…
As for morganite I have seen stones sitting in a crystallographers
display case loose colour over years, not exposed to sunlight…
I also have a question about kunzite and its susceptibility to
fading.
Should there be concern for displaying it in a store setting under
bright light?
Kunzite will fade either under sunlight, or just bright indoor
light. More slowly under less intense incandescent light. But in a
store setting, it oftem might be in a display where some heating will
also take place, and that, plus the bright lights, will fade it.
Store display lights are often the sorts with wider spectrums, like
halogen lights, that may include some UV. Those higher energy
wavelengths, either sunlight or artificial, fade the stones
quickest.
In general, Kunzite is best kept, and worn, away from bright lights,
Normal indoor lighting is usually OK.
