These lodestone chunks are naturally magnetized pieces of magnetite; note the iron filings which still cling to the rock when you remove it from the packaging as evidence. Lodestones were originally utilized as rudimentary compasses, but these days they make a great gift for a young scientific explorer or the geologically-inclined adult. Introduces fundamental magnetic concepts. Fun stocking stuffer; fool them into thinking it’s coal. ;)
