    Dear Kate, The rings you are seeing are growth rings. Since
    freshwater pearls are tissue nucleated, the bulk of the pearls being
    pearl nacre, they may grow at fits and spurts and create the rings.
    Saltwater pearls being bead nucleated will seldom have them as the
    nacrous coating is thin over the perfectly round bead. Hope this
    helps! Suzanne 

    ps. If you have a good library nearby, you may get alot of
    information reading Fred Ward's book on pearls. About $16.00 if you
    decide to buy a copy.
