I purchased heat treated chalcedony beads a couple of years ago and
used them in an 18K gold wire necklace. I recently took the
necklace on a trip abroad, carried them in my hand luggage. When I
arrived at my destination, I found that the beads had lost their
beautiful rich blue color and faded into a pale moonstone like
color. Someone mentioned to me that this might have happened when
they went through the airport xray machine.
I called up the retailer of these beads, Fire Mountain Gems, and
they indicated they were not famiiliar with this type of problem
and had no suggested solutions.
Does anyone have a similar experience with heat treated gemstones?
Was it really the result of the airport xray or something else?
Is there any way to reverse the effect without removing the beads
from the gold necklace? And if so, is it something I could do on
my own? Or are there any gemologists who specialize in this kind
I first joined the list in 1997 to pursue my jewelry making hobby.
It was the source of incredibly valuable I then moved
on to other things but now I’m back into it.
Thanks in advance for your help.
