    Some current high-tech coating, as polyurethane, can resist to age, maybe more than nacre itself. I repeat that pollution is maybe one of first factors to change brightness of pearls, years after years. About colours, the most sensible dyes are always those containing pink or red, because red (pink and yellow) is the first colour to be destroyed by UV rays (look at an old colours printed paper wich has received sunlight during a long time, it saved just the blue).

    I hope the difference in color hasn't discouraged you from wearing your earrings. The distance between them on either side of your head should keep the viewers from seeing both straight on at the same time. If it really bothers you perhaps PP can help you match another pearl to either one so you have a matching set. The other lone pearl could be a pendant perhaps?
    It's interesting to me how sometimes some pearls change and others don't. I don't have many pearls (yet, heh!) but only noticed this one pearl's difference. And when I did I thought this was the right place to come and ask. I'm glad I did. I value everyone's input and patience with me.

    I do love these earrings and will continue to wear them. I'll ask PP about it if the change in color becomes even more noticeable and maybe, like you said, they can match another pearl. Thanks for that suggestion!

    Eric is right. Each pearl grows and ages differently. Organic gems have their charms and their drawbacks. But we love them just the same.
    I make sure all my jewelry cloths are clean -- this is good advice as dust is abrasive and that's the last thing I'd want to do with pearls!

    Hm...haven't used the wet hand method, but have been using a clean, moist cloth -- I like your suggestions better and will try it.

    Thanks!

    I just looked at every pearl I own. A large number of them are FWP, including assorted metallics and exotics in white and natural colors. I am an eclectic buyer so these come from multiple vendors.
    Edit: One FW pendant might have a bead in it; the rest of the FW are solid nacre.

    With the exception of the one AA/AA+ FWP strand I mentioned previously that has gone a bit creamy (but is still lustrous) I do not see any degradation in luster or color in any of my pearls, including assorted metallic FWP and including my lavender pearls.

    Pearl Dreams - it is the bead nucleated "Edison" pearls that seem to change colour with time not the "solid nacre" freshwaters.

    I wonder if the color change in the Edisons has anything to do with a combination of the pigments in the outer layers of nacre fading, and the translucency of the nacre itself allowing the bead to show? That might explain tissue-nucleated freshwater pearls not discoloring?

    Just a guess. I haven't been collecting pearls that long and haven't noticed any discoloration in my small collection.

    I think it's a question of architecture of the nacre. I have observed that many freshwater pearls, edison and often lavander nucleated pearls, have more conchyoline layers parallel to the surface than right, even sometime thick layers without aragonite at all, also. As these layers give colour to the pearls, their particular layout can make them more sensible to UV rays. Against that, none nucleated pearls and saltwater pearls have a more homogeneous nacre, where it seems that conchyoline is spread by the same manner in any directions, and compound conchyoline /nacre is regular , wich give same nacre colour outer or deeply and maybe this better colour durability.
