The ingenious "Mom" mothers bracelets features a sturdy, yet invisible, clasp (you'll recognize the clasp because it is set with a cabochon sapphire). Also, notice how her most cherished name "Mom" encircles the wrist, with space to add birthstones or diamonds.
These bracelets are heavy weighted bracelets (not lightweight bracelets which you will find a lot of online) that allow you to add up to 15 stones, now or at a later time.
