    I'm wondering if the chemicals (if any) used to process the pearls have caused this color change. I'm not an expert, though, so I can only guess.

    I am not sure that so many FWP than belief are dyed. Strong colours are the most probable, of course. I have met rare peach dyed pearls, but it's always on surface, and dying seems difficult to make deeply. Often, if you rub during five minutes smooth colour dyed pearl with acetone on a white paper tissue, you might see a little bit of colour to appear on the white, and pearl lose its colour. Now, aragonite can be strong dyed, unlike calcite, by some chemical reactions, with silver nitrate, mostly.
    If you want to play, Pareltje, you bath your pearls first in silver nitrate, and after in potassium bichromate... They will turn in scarlet red, like cherries...

    Holly Molly! THAT's a BIG change!!

    I have one lilac strand that went lighter, sort of pinkish now, but I never properly wore it and assumed that's what affected it.. the others I have, like whites, goldens and deep purples are fine.. only had them for a couple of years though

    Years ago there was a fraudulent member claiming to own a strand of rare, supposedly-natural red pearls she called Lop Noors (which are non-existent.) People who have been on P-G for a long time might see it as an inside joke.
    That is all.

    OK!... And I have put my feet in my mouths (les pieds dans le plat, in frensh).
    I am really glad to make you so laughing!
    In fact, it's a usual way to make difference between aragonite and calcite in mineralogy (which is one of my hobbies).
