These tasteful bookends feature beautifully preserved ammonite fossils embedded front-and-center in slabs of polished black rock. Spruce up your shelf; just put books between each end to both hold books in place and accent your normally drab bookshelf with an original and natural piece of art. Each bookend also contains orthoceras fossils scattered about the slab, enchancing the aesthetic appeal. This is a unique gift that is both scientific and stunning in form. We highly recommend this item for Mother’s or Father’s Day gifts, holiday gifts, or for your favorite co-worker!
