Baby Nurse, your collection kills me. Those are gorgeous with that pale pink top.
After a cultured pearl is removed, the oyster or clam or mussel is returned to the water and a new pearl grows in the old pearl sac without having been seeded with new mantle tissue and without a new bead. The pearl is 100% nacre, but usually not round. Mine look roundish in the middle where the pearl sac held the original cultured pearl, and then flat and long where the slit was made for the insertion or removal of the pearl, I think.
