<p class="MsoNormal"><span style="color:#1F497D">Hi Cortney,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Just as there is variability in the colors of kunzites there is variability in their light-fading sensitivity. Those two variabilities arise for similar reasons – differences in energy gaps between various electron
‘traps’ (see Nassau 1992 In: F. Howie (ed.) Care and Conservation of Geological Material: Minerals, Meteorites and Lunar Finds. Butterworth Heinemann, London, 1992).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Knowing the locality and collection date could lead to less uncertainty in predicting light fading rate for your specimen – if you can draw on specific experience from another collection – but it will not lead
to certainty.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>

<p class="MsoNormal">Hello all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve had a request to loan a piece of early, very bright pink kunzite for a museum exhibition. Our chief gemologist has been unable to find any concrete information for how quickly kunzite fades and under what light and temperature conditions.
Would anyone be able to share guidelines for displaying kunzite to prevent fading?
