                                                          The "mother of pearl" is common for mother daughter jewlery.  You could get matching necklaces that each have a pearl on them. Or go more personalized and have something engraved with your names, initials, or a quote that is important to both of you.  You'll want to pick something timeless, that you'll both continue to wear forever.
