Geodes are a peculiar wonder of nature; they are formed from fluids which crystallize in cavities within a rounded rock or nodule. This means that what may seem to be a simple rock could very well be a geode, its core hiding a treasure trove of beautiful and intricate crystals. Geodes can be broken by being placed in a bag or sock, then hit firmly in the center with a hammer. Breaking your geode makes for a great family activity and the end product makes a great desktop decoration and an interesting conversation piece for any office. This geode would also be of great use for teachers in a classroom environment or for geology buffs.
Warning: Breaking geodes can be dangerous--safety goggles and adult supervision are recommended.
Note: Please be aware that this is a natural mineral and as such each piece is one of a kind! The one you receive may not be exactly the same as the ones pictured but it will be similar. Price is per each piece. They come in irregular shapes, sizes and weights.
