This set of two bookends has been formed of natural mica and resin. Created to showcase the beauty of the natural crystal encased within each block, no two will be the same. These make an absolutely stunning addition to any bookshelf or mantle and come in light and dark options: gray mica with clear resin or clear mica with pearl resin. Made of natural Mica stone. Each stone is unique, colors will vary and no two will be identical.
