These unique, engraved, cut stone bookends will spruce up any old bookshelf! Bookends make a great gift for retirement, graduation, housewarming, anniversaries or weddings. We start by selecting an all natural river rock. Then we cut off the bottom of the stone so it will easily stand upright on a shelf. Finally, before engraving, the stone is cut down the middle so your set lines up perfectly with the unique shape of the natural stone.
